Connectivity is one area where the C7 improves on the Samsung Chromebook Series 3. It might not have the Samsung’s USB 3.0 port, but makes up for it with three USB 2.0 ports to the Samsung’s one, plus HDMI, VGA and headphone outputs.












 
There’s also an SD memory card slot at the front and an Ethernet port on the left-hand side; one thing which the WiFi-only Samsung couldn’t boast. USB 3.0 is still most useful for connecting external storage, so on a device designed to work with cloud-based services its omission isn’t a fatal flaw. Overall, the C7 provides a better balance of ports and sockets.

Ergonomics

Unfortunately, the C7’s smaller desktop footprint comes at a cost. Where the Samsung Chromebook has a relatively luxurious keyboard with generously sized keys, not to mention a surprisingly big touchpad, the Acer has to manage with only slightly smaller keys, but a more cramped layout. The Chrome OS-specific function keys in the top row are tiny, while the cursor keys are ridiculously minute. The hash key is actually jammed against the return key, and ditto for the backslash key and the left-shift.

However, It’s not all bad news. The trackpad might be smaller, but it feels marginally more responsive than the one on the Samsung, particularly when it comes to two-finger gestures for scrolling or right-clicking. Meanwhile what’s become a Power button on Samsung’s Chromebooks, here returns to its original role: Delete. While I prefer the crisper typing action on the Samsung, I wouldn’t call the C7’s keyboard a disaster by any means. In fact, I’m using it to write this review right now, and barely missing a keystroke.

Screen and sound

The screen on the C7 is better than the screen on the Samsung Chromebook. It’s brighter, there’s more contrast, and whites look genuinely white and not slightly yellow. While it’s a TN screen with all the narrow viewing angles that implies, it still beats most netbook screens and even many budget laptops stone dead. The 11.6in size and 1,366 x 768 resolution match the Samsung, and the only advantage the latter is left with is that the matt surface will fare better in more lighting conditions than the Acer’s glossy coating.

When you’re looking at photos or watching video, the C7 delivers stronger pictures and better colours every time. When it comes to sound, the C7 is a little less impressive. It’s hard to get a beefy output out of a laptop this size, and even harder when you’re doing so on such a tight budget. The Acer’s audio is weak, tinny and lacking bass and clarity. If you want to stream music or watch a film you’d better plug some headphones in.

Software

Having only just covered Chrome OS in the Samsung review, we won’t go overboard on it here. The important thing is that Google’s cloud-based OS is now ready for primetime. It has apps to cover most needs and scenarios, it supports a more conventional Windows-like UI with multiple windows, and the old complaint that a Chromebook is useless without an Internet connection no longer holds water. You can work on documents, spreadsheets and presentations offline and sync changes when you next connect, and you can also read and answer emails. The built-in file handlers for video, photos and PDFs offer more features and are easier to use, and file management as a whole is no longer a disaster.
I still wouldn’t want to use a Chromebook to do heavy-duty photo or video-editing, or even use one as my main PC, but as a cheap, highly mobile, secondary computer it’s perfectly adequate for everyday use. There’s zero maintenance, and it doesn’t waste your time. What’s more, the way Chrome OS works, with everything tied into your Google account and your desktop and app selection changing to match, makes a Chromebook perfect for sharing with a family, an office or a class. There’s not much of a learning curve when it comes to using it, and the more I use Chrome OS, the more I like it. Understand the limitations of working across an Internet connection - particularly in low-bandwidth situations - and you’ll probably feel the same.

Performance

There’s good news and semi-bad news when it comes to performance. Acer’s decision to go with a 320GB conventional hard disk instead of an SSD probably makes sense from an economic standpoint - the C7 is clearly a re-purposed Windows laptop - but it means this Chromebook starts up slightly slower than the Samsung, taking roughly 19 seconds. This isn’t a massive issue, and the C7 doesn’t feel at all sluggish in everyday use, but it is peculiar. After all, it’s not like the cloud-centric Chrome OS is really built to capitalise on a larger drive.
On the good news front, the Celeron-powered C7 performs slightly better on intensive tasks than the ARM-powered Samsung. Where HD video streams stuttered every few seconds on the Samsung, they run reasonably smoothly on the Acer, and games like Bastion are just about playable. The C7’s SunSpider benchmark score is faster than the Samsung’s, at 523.1 to 758.2, and the WebGL Aquarium demo runs at a smooth 60fps to the Samsung’s 36 to 45fps. If you want to play 3D games then you’re barking up the wrong tree with a Chromebook, but you might want to watch films, and in this respect the Acer has the Samsung beat - though we hope to see software updates improve the performance from the Samsung’s perfectly capable Exynos SoC.

Battery life

Sadly, we’re back in netbook territory when it comes to battery life. Acer and Google claim up to four hours, but that really is best-case scenario. While working with the Chromebook we’ve seen around three and a half hours of mixed use with screen brightness at acceptable, near-maximum levels, and a lot of video will drag that down to the three hour mark. This isn’t a problem if your Chromebook will stay rooted to a table or a desk, but a device like this is built for action anytime, anywhere both in and out of the house. The Samsung Series 5, with a life of around six and a half hours, could handle that role with ease, but here the battery life of the C7 is a real limitation.

If there was a Windows machine to rival the mighty MacBook Pro, the Dell XPS 15 would be it. Dell’s latest offering has bleeding-edge specifications, a fantastic HD screen and great usability. Of course, it’s all wrapped up in a gorgeous silver chassis typical of the XPS range.

Taking the fight to other top-tier laptops like the HP Envy 17 and the Sony S Series, the Dell XPS 15 boasts an Ivy Bridge processor, dedicated graphics and a full 1080p Gorilla Glass display. Trust us, the result is seriously impressive.  

Dell XPS 15: Features

Dell’s customary XPS chassis hasn’t changed drastically despite several updates. The silver brushed metal chassis still looks fantastic and is offset with the black interior, complete with an isolation-style backlit keyboard. There’s not a hint of cheap plastic, and the glorious screen is almost bezel-less, meaning that the XPS 15 could be mistaken for a 14-incher.

Elsewhere you’ll find a built-in Blu-ray drive, 8GB of RAM and a 1TB hard drive. There’s no solid state drive, so start-up can seem a bit sluggish – especially when compared to super speedy Ultrabooks – but once it’s out of the blocks this machine goes strong even under heavy strain from multitasking.

If there’s one criticism that could be levelled at the Dell XPS 15, it’s the weight, and while the Apple MacBook Pro has been on a diet, this 2.5kg model is still a burden to carry.

Dell XPS 15: Screen

Fans of 1080p high definition video need look no further than the XPS 15. Dell has crammed 1,920 x 1,080 pixels on to the 15-inch screen which has been crafted from Corning’s Gorilla Glass.

There’s very little reflection from the glossy finish and viewing angles are excellent thanks to the 350nit brightness.

Dell XPS 15: Performance

The Intel Ivy Bridge CPU inside the XPS 15 stormed through our benchmarking tests and totally outperformed even the top-level second generation Intel-powered laptops. No matter what programs you’re looking to run – from video editing software through to Minesweeper or Online Scrabble, this machine can handle it.

Our gaming benchmark scores were some of the highest on test, thanks to the Nvidia GeForce 640M processor with 2GB of dedicated video memory. The XPS 15 tapped out with the likes of Battlefield 3 on full detail settings, but Batman: Arkham City ran without any problems.

Dell XPS 15: Battery

We tested the XPS 15 out with some looped 1080p high definition video, on top of a high-performance benchmarking program and the battery gave out after 226 minutes of continuous use.

We expect any machine at this price point to hit well above the 200 minute mark – so in fairness we’d have to say this is an average result. We’d ideally like to see the XPS 15 pushing for 300 minutes. However, with conservative use you can probably squeeze five hours from this machine.

Dell XPS 15: Verdict

Criticising the Dell XPS 15 is a bit like taking a crack at Helen of Troy - we could do it, but history doesn’t remember such transgressions. If you’re looking for a laptop that combines enough power to multitask your most demanding programs and look good doing it, then you’ve arrived at the right review.

The amazing HD display, great usability and Ivy Bridge power are all standout highlights and make the Dell XPS 15 the inevitable Windows alternative to the Macbook Pro. This is easily one of the best laptops we’ve ever seen.
