Microsoft Surface Book review Microsoft has finally done it: it's created a laptop that can replace your tablet. Wait… that doesn't sound right. Jokes aside, I wouldn't blame you for being confused by the Redmond Campus's latest creation, the Surface Book – a super premium laptop-based hybrid device – when it looks to have finally cracked the nut on the tablet that can replace your laptop with its Surface Pro 4. By all means, none of this is to say anything of the Surface Book itself. Microsoft has arguably produced the most versatile, inventive and gorgeous Windows laptop ever made. But it's tough to envision where this aluminum-clad notebook fits within Microsoft's market-leading product lineup when it's effectively created a laptop and tablet within a single device – twice. For now, let's take a closer look at the absolutely pristine laptop that Microsoft devices team lead Panos Panay and his crew have expertly crafted. Design and display The Surface Book truly is a sight to behold, and that's not an overstatement. Like the Chromebook Pixel, Microsoft's take on the laptop employs unique dimensions all around. That super sharp, color-rich 3,000 x 2,000-pixel screen measures 13.5 inches at the diagonal, while the device is just 12.3 inches wide. This is because 1.) Microsoft achieved some extremely narrow bezels 2.) the screen fits a 3:2 aspect ratio, just like the Surface Pro tablets and 3.) the screen's height is closer to that of a laptop with a 14-inch screen, at 9.14 inches. And like both the Pixel and 13-inch MacBook Pro, the Book is a bit hefty altogether at 3.48 pounds. At that resolution, the Surface Book touts 267 pixels-per-inch (ppi), edging out the MacBook Pro's 227 ppi and the Pixel's 239ppi. Colors on the screen simply pop, and it's incredibly responsive to touch, thanks to Microsoft new, trademark PixelSense technology. Simply put, it brings the optics and touch controller elements closer to the glass than ever before. Oh, and the screen sports a 1,800:1 contrast ratio, making for some seriously deep blacks. The laptop is cased entirely in brushed magnesium and, just like its Pixel and MacBook Pro rivals, features a pronounced lip in front of the awfully smooth, glass-laminated trackpad for easy opening. I also found the keyboard to be wonderfully comfortable to use, with deep enough travel and a great amount of punch. Opening the laptop is made even easier by Microsoft's also-trademark Dynamic Fulcrum hinge. Looking like a tiny metal gauntlet, this inventive new hinge serves one important purpose: increasing the surface area of the laptop's base to counter the weight of the tablet it's attached to. A bonus: it looks just so damn cool. Sure, this new hinge leaves a sizeable gap between the display and keyboard when closed. But, because it closes in a sort of semicircle rather than flat, like most other hinges, it makes for a comfy hold when toting about. Microsoft's 'One More Thing' Panay wowed the audience of journalists, analysts and Microsoft fans during the Surface Book's reveal with a sort of "One More Thing" moment: he detached the screen from the laptop base. Not only is this Microsoft's first laptop, it's also the firm's third hybrid device. The way in which the tablet – which Microsoft refers to as a clipboard – fits into the base is so seamless, that many (including this guy) couldn't have guessed that reveal. But more importantly, that seamless transition makes for the first 2-in-1 laptop taking the laptop-first approach to truly impress me both aesthetically and functionally. Microsoft achieved this through what it calls a Muscle Wire detach mechanism. In conjunction with some powerful magnets, this mechanical solution makes for an incredibly strong connection – so much so that you can hold the laptop open by either end and not worry. Basically, every detachment of the tablet from the keyboard base requires you to press a special key on the uppermost row of the keyboard to release these tensed wires. Once that's done, a green prompt will tell you it's OK to remove the tablet. (Of course, the tablet can be attached in either direction.) Why all of the hoopla over just attaching and detaching a tablet? That's because Microsoft managed to house a custom-built Nvidia GeForce graphics chip within the base. This allows the Surface Book to handle far more graphically complex tasks when in one piece, while allowing the tablet to operate on its own with an Intel Core i-series processor inside. Plus, the system is smart about when the GPU is in use, warning you before removing the tablet through a similar green prompt. This is all thanks to Microsoft's proprietary Surface Connector used throughout the product line, which offers enough bandwidth to manage such intense graphical tasks, not to mention communication between the CPU and GPU.

Dell XPS 15 (2015) review The 2015 version of the Dell XPS 13 added an unexpected gem to the company's arsenal back in January. Sleek, powerful and packing a gorgeous Infinity Display, it ramped up the company's reputation in the consumer space and served up a real alternative to 13-inch Apple's MacBook Air. The new Dell XPS 15 carries over the XPS 13's Infinity Display, which makes it one of the most compact 15-inch notebooks around. Just as the XPS 13 managed to be around the same size as the 11-inch MacBook Air while cramming in a 13-inch display, the XPS 15 is only slightly bigger than the 13-inch MacBook Air. Lying one on top of the other, you can see that the XPS 15 wouldn't give you that much less space than the Air when slung into a backpack. At 3.8 pounds, the XPS 15 is noticeably heavier than the Dell XPS 13, but when you consider that it's a 15-inch laptop with dedicated graphics inside, you can't really complain. There's another advantage to the XPS 15's 15.6-inch display in that it has a higher resolution than the XPS 13. The Dell XPS 15 can be configured with up to an UltraSharp 4K Ultra HD display, which offers a pixel-resolution of 3,840 x 2,160. That means that with even with Windows scaling set to 200%, which makes fonts look incredibly crisp, you still get the same amount of space on the desktop as a 1080p monitor. In comparison, the XPS 13's 13-inch QHD+ display only gives you the equivalent of a 1,600 x 900 monitor, meaning you get a lot more space on the desktop to snap apps and be productive on the new Dell XPS 15. The XPS 15's desktop wallpaper and the fonts in Notepad were on another level of clarity to non-4K displays, so much so that it would be difficult going back to anything else. In terms of performance, the XPS 15 packs muscle underneath the hood. It can be configured with up a sixth-generation Skylake Intel Core i7 Quad Core processor backed up by up to 16GB of fast RAM clocked at 2,133MHz. The Dell XPS 15 even promises to appeal to gamers though the option to equip it with up to an Nvidia GeForce GTX 960M graphics with 2GB of GDDR5 memory. It's equally up to speed on the connectivity front thanks to the inclusion of a Thunderbolt 3 port, the newest generation of Type-C connectivity that provides up to eight times the transfer speeds of USB 3.0 (up to 40Gbps, in other words). You'll be able to use the Dell XPS to power up to two 4K displays, which should provide more pixels than you know what to do with. The Dell XPS 15 can be equipped with a Full HD display, rather than a 4K variant, which the company claims can go for up to 17 hours on a single battery charge. Dell hasn't provided any battery life figures for the 4K version we tested, but you can expect it to achieve at least three or four hours fewer. The XPS 15 is once again available with an external battery pack that can be used to juice it up on the move. While a subjective point, I was never too enamoured with the Dell XPS 13's keyboard. Its chiclet-spaced keys were well-spaced but felt shallow, something that was put down to that machine's thin dimensions. It seems that wasn't the case, as Dell has ported over the exact same keyboard to the slightly thicker Dell XPS 15 - and it feels just as unsatisfying to type on. It's bizarre that Dell has chosen to fit its most comfortable keyboard in recent memory on its new Dell XPS 12 hybrid, which is a much smaller 12.5-inch device. If Dell had used the same keyboard on the new XPS 15 then it would have ticked every box going.
