A chassis that thin leaves little room for cooling, for example, and it does have a tendency to get a little toasty if you push it too hard. That's very portable indeed (if not quite as portable as the Acer Swift 7) but it may also have its downsides. It's also amazingly petite, weighing just 774g (sans keyboard) and measuring 7.3mm thick. The round edges look much more generic than the distinctive angles and lines of the Pro's frame, and while matte black is a safe, professional colour, making it the only option is a shame when the rest of the range is so vibrant. It's attractive enough, although a little dull-looking compared to the regular Surface Pro. The design of the Pro X is immediately familiar it's essentially just a more rounded (and thinner) version of the well-established Surface Pro design.

The rub, however, is that it can’t run the full gamut of x86 Windows apps. The Pro X is designed to take advantage of 4G connectivity and uses a Qualcomm chip in order to maintain strong battery life while it does so. This may sound like madness, but there’s method to it.
