This new category of PC can be hard to pin down. To some, these are all-in-one desktops, similar to the Apple iMac, but with the added ability to either fold down flat or detach their screens. To others, these are battery-powered megatablets, with screens measuring between 18 and 27 inches, but are otherwise similar to Windows 8 slates such as Microsoft’s Surface Pro. But, I think they’re an entirely different animal, with features of a personal computer, a piece of consumer electronics equipment, and even living-room furniture.
None of the early examples are quite ready for broad mainstream audiences yet, but of these, the 18-inch Dell XPS 18 is thin and light, and it’s the easiest to carry around, while the Lenovo Horizon is the most ambitious, with a giant 27-inch display, custom software interface, and a small collection of included accessories for tabletop gaming.
