Apple to stop Mac Pro sales in much of Europe on March 1



Apple today told retailers and distributors in most European countries that it will stop selling the Mac Pro on March 1 because the desktop system doesn't meet electrical regulations.
The Mac Pro's ports and fans don't comply with a new amendment -- which goes into effect at the beginning of March -- addressing safety and electrical standards for electronics, according to Macworld. An Apple spokesman confirmed the decision to CNET. The regulation affects the 27 countries of the European Union, which includes the U.K., Germany and France, and the four countries in the European Free Trade Association (EFTA) -- Iceland, Liechtenstein, Norway and Switzerland. Although Apple itself will stop its sales of the Mac Pro, Apple resellers will be able to sell any remaining inventory after March 1.

Review Gigabyte U2442N Notebook

It has been a while since we tested a Gigabyte model. The Taiwanese manufacturer is famous for its motherboards and peripheral devices. Gigabyte also offers a small selection of tablets and notebooks.

The Ultrabook creator, Intel, prophesised a boom in the Ultrabook market in the near future and many manufacturers, including Gigabyte are investing in this area. The new Gigabyte U2442 is a second generation Ultrabook which runs on the Ivy Bridge architecture.
The U2442 series has a 14-inch display, and places alongside Ultrabooks like the HP Envy 14 Spectre and the Acer Aspire Timeline Ultra M3. The notebook is not equipped with ULV components, but with a fast Core i5-3210M and the middle-class GeForce GT 640M graphics card. Officially, the U2442N cannot qualify as an Ultrabook with this hardware and only its sibling, the U2442V (identically equipped but with a ULV CPU - Core i7-3517U) can wear the title.
The rest of the hardware is similarly potent: 8 GB RAM, a 128 GB SSD and a 750 GB hard disk. This hardware is top class, which brings us to the price: (starts at) 1200 Euro (~$1555) for the U2442N. Other Ultrabooks are similarly expensive, so we will see what the test model can do in the following review.

Case

Smooth hinges
Smooth hinges
Made in Taiwan - the manufacturer is quite proud of this fact as can be seen by the large sticker on the top right of the screen. Our first impression is neutral: the silver-grey case is made of synthetic material and aluminum, yet it does not look as flashy as most competitors and may even be slightly drab. Thankfully, this is very practical as dust and smudges would be far more visible on darker (and even high-polished) cases.
The bottom of the laptop is made of only plastic, yet it offers good sturdiness. The chassis bends slightly under the keyboard when excessive force is applied. With the exception of this, the test model is as sturdy as a laptop with a metal chassis. This is especially impressive as the U2442N is a mere 21 mm thick and weighs 1.69 kilograms/3.72 lb. (and without the HDD - a mere 1.59 kilograms/3.5 lb.). Overall, the test model is very mobile. However, if the display bezel was thinner (between 1.5 and 2.7 cm), the mobility could be increased further.
The back of the display is made of polished aluminum, as promised by the manufacturer. This ensures that the display is quite sturdy. Thanks to the well-designed hinges, the laptop can be opened with one hand. On the other hand, when the laptop shakes, the display wobbles. We did not find any workmanship flaws like sharp edges, which results in the Gigabyte U2442 receiving a good score in this section.

Connectivity

Like many other notebooks of 2012, the Gigabyte U2442N has two USB 3.0 interfaces. In addition, the laptop offers two USB 2.0 ports and this should satisfy most users. It is a real pity that the test model lacks a (Mini-) DisplayPort interface, but the user is provided with both a VGA and a HDMI interface.
The test model has no optical drive, ensuring that all ports have sufficient space on the case. The layout chosen by Gigabyte is well thought out and practical: Gigabit-LAN, the power outlet and both display interfaces are placed towards the back of the case, whereas the USB ports (two on the left, two on the right) and audio jacks are placed towards the front. All the interfaces and the card reader, which can only read SD cards, can be used without issues.

Communication

The Intel Centrino Wireless-N 2230 is a mini PCIe WLAN module, which offers features and performance appropriate for a middle-class device. The Multi-Stream technology (2x2) makes it possible to transmit and receive up to 300 MB/s, but only on the usually overcrowded 2.4 frequency. The model does not support the 5 GHz frequency which means that users are limited to just one band on IEEE 802.11b/g/n networks.
The U2442N also has Bluetooth 4.0 (provided by the same module). This new standard of the wireless technology has a special Low-Energy mode and is supported by many modern Smartphones.
As usual, a small 1.3 megapixels webcam is installed in the display bezel. It may not take sharp pictures but it suffices for use with Skype or similar programs. The integrated microphone is of similar quality, and, in most cases, the user will not require an additional microphone.

Accessories

We did not expect this: the manufacturer offers a typical delivery (manuals and a driver CD) and includes a stylish leather bag. Although the material is not very high-quality, most users will be happy about this small extra which ensures more protection for their device.
The software extras are scarce. Thankfully, this means that the user will not have to uninstall unnecessary test versions. The obligatory Adobe Reader and Starter edition of Microsoft Office 2010 are pre-installed and can be accessed via desktop shortcuts.

Maintenance

Few upgrade possibilities are a characteristic of compact notebooks. This applies to our test model as well. The bottom of the model has a flap, which is secured by a single screw, and covers both RAM slots. These slots are already occupied and upgrading to 12 or 16 GB is only possible after removing the installed modules. All additional components, including the integrated battery, cannot be removed easily.

Warranty

Gigabyte promises 2 years global warranty for the U2442N. If the laptop should break down in a foreign country, the user can get it repaired on-site at a  Gigabyte shop. We could not find any information or offers pertaining to an extension of the warranty.

Input Devices

Keyboard

The chiclet keyboard is installed nicely, if not perfectly, in the chassis of the test model. The workmanship and sturdiness are very good and it did not bend much even under immense force. We did not appreciate the cheap quality of the material of which the 15x15 millimeter keys are made. The integrated backlight helps the user type easily in the dark which is a positive. Gigabyte has used a standard layout for the keyboard (US keyboard for our test model).
The soft pressure point is noticeable while typing but, in our opinion, it does not provide enough feedback. The pressure point is paired with a short stroke distance (typical for notebooks). The typing experience was diminished due to the steady clattering of the keyboard which accompanies high-speed typing. We expected much more of a notebook of this price range.

Touchpad

The Smart-Pad made by Elan performs better in our review. The device measures 5.3 x 9.6 centimeters, and although it is not very large, it has some good qualities. The rough surface reminds the user of Lenovo ThinkPads and may not be to the liking of all users, but the sliding properties are amazing, even with sweaty fingers. The precision and offered features are also quite good. The touchpad supports the typical multi-touch gestures which can be individually configured or de-activated (the touchpad can be switched off by pressing Fn + F10).
A broad button below the pad performs the function of both mouse keys. The stroke distance is short, like the keyboard, but thanks to the strong pressure point the user can comfortably use the touchpad. A practical feature: pressing the right mouse button while the laptop is off will show the battery charge. The 5 status LEDs are used for this task as well as for showing the activity of the wireless module while the laptop is on.

Display

Gigabyte has picked a matte WXGA++ display for its 14-inch model. The screen has a resolution of 1600 by 900 pixels which translates to a nice pixel density of 131 dpi. This provides the user with a well-sized work space and an acceptable font size.
At the maximum level, we measured an average brightness of 233 cd/m². Near the bottom of the screen, the brightness drops to a little above 200 cd/m², causing a slightly unbalanced illumination of 83 percent. However, in our use, this was only noticeable when looking closely and should not affect the everyday user.

Distribution of brightness
Buyers expecting a high-quality IPS panel like in the Asus UX31A or UX32VD, will be disappointed by the simple TN screen (LG LP140WD2-TLD2) of the Gigabyte U2442N. Sadly, although the black value (1.47 cd/m²) and contrast (161:1) are decent, they just cannot match the values of a high-quality panel. This is a common problem for many notebooks like the U300s from Lenovo.
The limited color space coverage is another weakness. The sRGB and AdobeRGB standards, very important to photographers, are only partially covered. This means that the user would have to connect an external monitor for professional picture editing. In our test, we noted that the red shades were especially hard to differentiate from one another.

The matt display surface will not cause too many distracting reflections during outdoors use. However, the brightness, which is already quite low, drops 10% while the laptop is running on battery, making the use of the laptop outdoors in direct sunlight quite hard. We would have liked to have a brightness of at least 250 to 300 cd/m² for outdoors use. The Samsung 900X4C is a good example.

After finding so many weaknesses, we expected the TN panel to perform below average in the viewing angle stability test. Our suspicion was confirmed: even the slightest movements from a central sitting position can deteriorate the picture quality significantly. This applies to both horizontal and vertical viewing angles. The U2442N is not the ideal choice for viewing a movie with many friends.
Buyers who want to use an external monitor with the laptop should get one which has a HDMI interface. Although the VGA output is clear, the picture is tinted slightly yellow. The color settings in the graphics driver can be used to ameliorate this issue.

Introduction
Going to Las Vegas for CES 2013 was great, obviously. However, apart from the opportunity to eat your own body weight in steak and lose your rent money on blackjack, it is one hell of a tiring six or seven days.
Therefore the last thing you need after coming back from walking 12 miles around the show floor is having to deal with a slow and buggy laptop. What you want is something you can rely on, which will boot up fast, and wont run out of battery the minute  you move your hand toward the plug.
Therefore it was with a mixture of trepidation and excitement that I accepted delivery of an touchscreen Acer Aspire S7 the day before flying out to Las Vegas last week. Trepidation because I had no idea if Acer's latest Ultrabook was going to be stand up to the rigours of CES; excitement because this is one of the fastest and best-looking laptops on the market today.

Acer Aspire S7: Design
As Ultrabooks go, the Aspire S7 is a beauty. It is sleek, well-built and has enough original touches to make it stand out from the crowd. Acer's previous effort at an Ultrabook, the pedestrain Aspire S5, wasn't even in the same league as the S7 - despite that odd motorised mecanism for revealing/hiding the ports.

The lid of 13in S7 is clad in Gorilla Glass to give you extra protection from scratches and scraps, and it meant putting it in the rather odd case that came with it, not a necessity. I should note however that the 11in version of the S7 comes with an aluminium lid rather than a glass lid, making it more prone to scratches I imagine.
White is traditionally not a colour associated with premium consumer electronics devices, but Acer has made it work. Open the lid and the great design and finish continues with the Chiclet style keys and trackpad floating in a sea of aluminium.
On first viewing I thought the screen had a white plastic bezel around the edge, but in fact it's all part of a single glass sheet covering the screen, which again ACer has carried off really well.
At 1.3kg and 12mm thin, the Aspire S7 is thinner and lighter than the MacBook Air and I had no problems carrying it with me during long treks around Las Vegas. It was also well able to stand up to being thrown around in a backpack surviving the week unscathed.
Acer Aspire S7: Keyboard and Trackpad
As I said, the backlit keyboard and trackpad as well as the surround seems to have been hewn from a single piece of aluminium. The keys themselves are very shallow, continuing Acer's trend of late, and don't offer the kind of satisfying response that we got from the keyboard of the most recent Dell Ultrabook and convertible.
That said, I really like the keyboard, and found typing on it was easy and pretty much mistake-free. This is thanks to the keys being responsive, well-spaced and, for the most part, nicely sized - though there are a couple of exceptions. The Caps Lock key is a narrow sliver almost impossible to press accurately withouth looking down at the keys, while the arrow keys are little better. I constantly found myself pressing the Page Home and Page End buttons which are right next to the arrow keys.

The TrackPad however, has few redeeming features. It seems as if Windows OEMs struggle to compete with Apple in this most vital of areas.
Where Apple's trackpads are responsive and nimble, Acer's was buggy and didn't work well with non-Windows 8 apps. Sure swiping in from the left to display the Charms menu, and swiping to navigate the new home screen worked OK, but try using it on the Tweetdeck app (for Windows 7) and it's a different matter. Vacillating between unresponsive and over-sensitive, it was a nightmare to use at times.
I also found the trackpad thought I was registering a left click even when my finger was nowhere near the bottom right-hand corner. It's a pity as it somewhat ruined the overall experience - though Acer did provide a Bluetooth mouse with my review unit which worked a treat and which I used whenever I could.
Acer Aspire S7: Screen
Whatever Acer's mistakes with the trackpad, it made no mistakes with the screen. Replacing the traditional 1366 x 768 resolution panel with a Full HD 1960 x 1080 display may seem like overkill on a 13in laptop - and it is really - but the result is simply superb.

One of the best screens we've seen on a laptop - with the obvious exception of the MacBook Pro's Retina display - the IPS panel offers wide viewing angles, great colour reproduction (without being over saturated or blown out) and great contrast. Glare is a problem, but that's something we've got used to on laptops at this stage.
This is of course a touchscreen and it's nice and responsive, and you can push the screen all the way back until it is flat with the keyboard - though I'm not sure if this will be of value to anyone to be honest.
Acer Aspire S7: Connectivity
Ultrabooks by their nature are going to have limited connectivity when compared to their chunkier notebook brethren, but Acer has done a good job with the Aspire S7 to give you what you need.

On one side you get two USB 3.0 ports, an SD card reader while on the other side you'll find a micro HDMI port. Sounds a bit limited? Well yes, but Acer also shipped the S7 with two adaptors for Ethernet and VGA ports which you plug into the HDMI port.
Working at CES the SD card reader was a vital addition and something which is sadly lacking on a lot of expensive Ultrabooks. The ability to use wired Ethernet was also a saving grace, with hundreds of other CES journalists in the press room hogging the limited Wi-Fi signal.
In terms of wireless you get the usual pair of Bluetooth 4.0 and Wi-Fi N.
Acer Aspire S7: Hardware, Performance and Battery Life
Of course a great looking laptop will only get you so far, and needs the power behind it in order to make it a valuable tool. The S7 comes with a choice of Intel's third generation Ivy Bridge Core processors, Core i5 or Core i7.
My review unit came with the 1.7GHz Core i5 chip, which was paired with the standard 4GB of RAM. Along with this was 128GB of SSD storage, which is upgradeable to 256GB.

The first thing you notice about the S7 is that it is LOUD. Even with just a couple of browser tabs open, the CPU's fans kicked in and this isn't a noise you can ignore. It's REALLY noisy and unless you are just sitting there looking at the laptop and not touching it, it's going to stay loud.
I can understand fans kicking in when you put the CPU under some pressure such as video editing or gaming, but browsing the web? This can make using the S7 a chore rather than a pleasure.
Trying to put the noise to one side, the Core i5 processor is very fast and carried out all we asked of it at CES with consummate ease, rarely slowing down, even with multiple programs open at once.
The dual SSDs, like in the S5, are arranged in a RAID 0 set-up, meaning read-write speeds are searingly fast compared to the competition, which makes the whole system tick along at a very fast pace indeed.
We did however encounter some bugginess during our time in Vegas, with the laptop rebooting randomly and freezing without notice. This could be an isolated problem with my review unit or a wider problem with the S7 - or then again it could be a problem with Windows 8.

In terms of boot time, the Aspire S7 was also on a par with other Ultrabooks, booting up from cold in just over 10 seconds and restoring from Sleep mode in around 3 seconds.
Moving onto battery life, and this was probably the biggest disappointment of using the Aspire S7. We managed no more than four hours of use away from a power supply during our week in Las Vegas, which is poor, even by Ultrabook standards.
Four hours is simply not good enough for a portable machine designed to bring with you wherever you go. Yes you might stretch five hours from the S7 with setting changed, but I don't think you should have to compromise that much in order to get decent battery life.
Acer Aspire S7: Verdict
The Acer Aspire S7 is a very frustrating machine. On the one hand it's beautifully designed with a magnificent screen, great keyboard and fast performance. But for a near-£1,000 laptop the dodgy trackpad, loud fan and inexcusably poor battery life are problems too big to ignore.
Acer has certainly upped its game from the Aspire S5, but a shiny new coat doesn't manage to hide a series of blunders which unfortunately spoil what could have been a great laptop. I'll have to chose more wisely for CES 2014.
