If three examples of the same thing marks a trend, then we're almost guaranteed to see more systems like the Dell XPS 18. Like the Sony Vaio Tap 20
and the Asus Transformer AIO
, the XPS 18 is a hybrid of the all-in-one desktop and the large-format tablet.
In practical terms, that means this is an all-in-one PC with a built-in battery that detaches from its included stand. You can keep it docked, in which case it's virtually indistinguishable from other AIO systems, or pick the 18-inch display up and go from room to room, or farther if you're feeling bold.
Why would you want to do that? We've found existing tablets to be very useful for quick information gathering or showing off photos and media, but too small for really sharing efficiently with a group (say, a family).
Unlike a large all-in-one desktop screen-stand combo that needs to be lugged from room to room, the 18-inch touch-screen display on the XPS 18 is easy enough to pick up and carry around. It even has two flip-out feet for standing up on its own, although I wouldn't count on them as stable enough for permanent use.
