If you already have a desktop at home, you should consider whether you actually have room for the full GX700 and its dock.My desk is occupied already by a gaming PC, so I had to relegate the GX700 to the dining table. This proved a problem at mealtimes, when the laptop had to be undocked and the whole shebang moved to another room in order to eat like a civil human being.Granted, I doubt those who can afford this laptop will share the space issues suffered by a lowly tech writer, but it’s worth considering if the GX700 isn’t your main machine.I was a little underwhelmed by the GX700's screen. It didn’t jump out as I'd have expected a panel on a high-end laptop to, with contrast and viewing angles in particular nothing to shout about.
This is a shame – although, in all likelihood, this laptop will spend much of its time hooked up to an external monitor. Still, second to performance, a laptop at this price should include a fantastic screen, and this one simply isn’t. At just Full HD resolution, too, it’s a little disappointing that you can’t push the GPU to its limits with 1440p or 4K gaming.Contrast was underwhleming: 0.35-nit black levels are pretty high and meant that atmospheric – and very dark – games such as Shadow of Mordor needed their in-game brightness jacked up just a little. Maximum brightness was pretty high at 365 nits, which lead to an overall contrast figure of 1,059:1. Normally, this would be a decent result, but on a laptop of this price I'd have wanted more.
An overall Delta E figure of 3.65 is pretty decent – where a lower number means more accurate colours – with most colours well served, if a little darker than I’d like. Reasonable marks for the screen, then, but it's far from outstanding.Acer has firmly placed itself back into the world of Ultrabooks, launching the brand-new 2016 Aspire S 13 laptop to take on the likes of Asus’ ZenBook UX305. Here are the four things I learned when I spent some time using it after its unveiling:It’s light at just 1.36kg, although its plastic shell does an awful lot to contribute. It looks great, though, available in both black and white with a stylish, textured lid and nicely finished keyboard tray.The keyboard itself feels great. It’s backlit and has a reasonable amount of travel to it, and the tray just has a little flex when you push down on it. In this area, at least, the Aspire S 13 doesn't give away its cheapness.
Like the just-announced Acer Switch Alpha 12, the Aspire S 13 will ship with Intel Core i3, i5 or i7 processors with the U suffix, meaning they’ll be low-power, dual-core chips. Don’t discount them, though, they generally have excellent performance in most modest tasks such as web browsing and document editing. They’ll also be capable of some light photo editing. I'd imagine the models in the UK will get 8GB of RAM, although a paltry 4GB might be a possibility.Acer reckons the Aspire S 13 will be capable of around 13 hours of battery life. I’m not convinced it’ll be that good in normal use, but with the screen brightness turned up, Windows 10’s fairly accurate battery indicator reckoned I had 8 hours to play with from 98% capacity. This could be very competitive if this makes its way to the final product.With a 13in Full HD, IPS screen, images look pin-sharp and contrast is excellent. Colours also look nice and vibrant, so I’m optimistic the Aspire S 13 won’t be let down by its screen, which many cheaper Ultrabooks do sometimes suffer from.
First impressions of the Dell XPS 12 are excellent. It's clearly a well put-together device, aimed at rivalling Microsoft’s increasingly convincing Surface tablets as well as the iPad Pro.Aside from the Gorilla Glass front, the rest of the unit is made from magnesium alloy painted in a soft-touch black finish. The result is a hybrid that's incredibly light yet strong and comfortable in the hand.This quality feel continues to the keyboard dock, which gets the same finish and feels reassuringly rigid. A quick tap of the keys and trackpad also suggest they’re premium-grade inclusions.The tablet is quite square, so it doesn’t nestle in the hand quite as well as an iPad. However, the XPS 12 really isn't the sort of tablet that's meant for casual, one-handed use. It’s just 12mm thick and weighs 790g on its own, compared to 723g for the iPad Pro, which is a noticable amount more.

Meanwhile, the simple flat back of the tablet allows it to rest securely on a flat surface, allowing you to type or draw on the screen without annoying wobbles.The dock and tablet attach via a set of gold contacts on the bottom edge of the tablet. Slot it into the slot on the dock and the magnets pull the tablet into place. A couple of plastic tabs help to stop the tablet from sliding around in the slot, ensuring the docking works flawlessly every time.The magnetic connection is so strong that you can lift up the entire unit by the tablet alone; the angled support means the tablet stays secure when picked up via the dock too.When you're finished working on the tablet it can be folded flat just like a laptop, thanks to the clever dock slot that guides the tablet round as you lower it. The pull from a further set of magnets takes over as the two get close, holding the sandwich together.
The operation works in reverse, too, allowing you to grab the front of the tablet and pull it open just as you would the lid of a laptop. Although it doesn't do anything quite so clever as bringing the tablet straight out of standby, it’s far easier than many other such systems.To complete the folio feel, a fabric-backed and rubber-lined magnetic cover wraps around the entire unit, with both stiff and hinged sections allowing it to sit flat on the tablet and dock while also bending as you open and close the device. The cover can even be used with only the tablet, and has a loop for storing a stylus.The huge downside to this whole system is that it adds considerable thickness to the dock. Where the slot section juts out at an angle, the combined tablet/dock combo is 24mm thick, which could potentially make the setup that little too big to slide easily into your favourite bag pocket or protective sleeve.
Also, unlike the Microsoft Surface Book, the dock doesn’t contain any batteries or any extra ports, nor does it boost the connectivity. Instead, it draws its power from the tablet and uses it to power the keyboard and trackpad.As such, connectivity is limited. The tablet includes two USB Type-C sockets – also compatible with Thunderbolt 3 – and a microSD slot. It’s great to see Dell embrace the new connection type, but the lack of full-sized USB sockets means that you’ll always need to carry an adapter (one is provided). Thankfully, you do at least get two Type-C sockets, so you can charge your laptop and plug in a second device without the need for an adapter – unlike the MacBook.Otherwise the tablet is entirely typical, with a power button on the top right edge (along with a Kensington lock slot), and volume buttons and a headphone socket on the left. Below the flap that covers the microSD slot is room for another slot, presumably for a SIM, but this feature hasn’t yet been added – at least to UK versions of the hybrid.
The XPS 12’s dock may only offer the addition of a keyboard and trackpad, but when they're as impressive as this, it would be churlish to complain. Plain and simply, they’re the best you can get for a tablet/dock system such as this. In fact, they’re as good as the very best you’ll find on a laptop.Admittedly the keyboard is slightly more compact than a typical laptop – it’s even slightly smaller than the already compact Dell XPS 13 at 358mm across – but it benefits from an excellent layout. For a start, it's actually a proper UK configuration plus all the major keys are close to full-size. The key action is excellent, too, with decent travel and a clearly defined break.The keys are backlit, with even a couple of different brightness levels from which to choose. I really can't overstate the usefulness of key-backlighting and thus how much it raises the status of the XPS 12 over most other hybrids.
My only complaint is that I’d have preferred the PageUp and PageDown keys to be made into secondary functions of the Up and Down keys in order to create a little space around the cursor keys.The trackpad is also superb. The etched-glass top is delightfully smooth and the single-click surface is responsive and has a defined but lightweight click. What’s more, the tracking is spot on and perfectly setup right out of the box – no need to tweak the sensitivity in the driver.Sleek and well built, the XPS 15 is Dell’s answer to the 15-inch MacBook Pro. Top-end processing power and dedicated graphics come together to produce what could be the ultimate Windows 10 laptop.It's up against some stiff competition from across the market, however, including high-profile devices such as the Microsoft Surface Book, more mundane but powerful laptops such as the Asus N552VW, and Dell’s own Inspiron line. This laptop has some serious work to do to justify its high price.
The model on review is the cheapest version you can buy. It includes a mechanical hard disk instead of an SSD, and is equipped with only an Intel Core i5 processor instead of the Core i7 chips found on higher-end models.Dell's XPS machines are renowned for their superb design, and the XPS 15 doesn't disappoint. The aluminium lid looks as good as ever, but it’s the carbon-fibre-composite wristrest that really catches the eye.Not only does it look fantastic, it’s comfortable to lean on too. There are no sharp corners and the slightly soft-touch coating puts some distance between you and the textured material below.

It was in the 2014 and 2015 XPS 13 laptops that we first saw the impressive, carbon-fibre-effect wristrest, and while it makes the move to the larger model successfully, I wish that the finish had been extended to the rest of machine. Note that the material does have a tendency to pick up greasy marks, which is a slight disappointment, but a quick wipe with a sleeve/cloth is enough to clear them up.Despite its 15.6-inch form factor, this particular model of the Dell XPS 15 weighs just 1.78kg. Higher-end laptops in the range, with a larger battery and a touchscreen, weigh closer to 2kg, so if portability is a priority then it pays to spend a little less.
This light weight can also be attributed to this laptop’s incredibly thin bezels. While a regular laptop may feature a bezel that's around 2cm in width, the Dell InfinityEdge display's top, left and right bezels are only 5mm – which does plenty for the laptop’s overall footprint. However, you do miss out on an integrated number pad as a result of the smaller overall size, which might be a deal-breaker for some buyers.At only 17mm thick when closed, too, the Dell XPS 15 will easily slide into any reasonably sized backpack. I rode it to and from work in my backpack on my bike and never felt like it was weighing me down.Dell has included a generous array of ports. There are two USB 3 connectors, a 3.5mm headphone/microphone combination jack, an SD card reader and a full-sized HDMI port.The XPS 15 also includes a Thunderbolt 3.0 port, which will be enticing to those who intend to use the XPS as their main machine for high-end workloads, hooking up high-resolution external monitors, a dock or high-performance storage.
