If you put them side by side (as we did), it's a pretty stunning difference, making one an essentially desk-locked system you can lug from room to room occasionally, and the other a reasonably portable lap-size tablet that can also stand upright when needed.īut if weight isn't your main concern, the HP Rove does has some serious advantages. The interesting part is that while the HP Rove and the Sony Tap 20 both weigh around 12 pounds, the XPS 18 manages to be an essentially similar machine at only a bit above five pounds. A comparable model is $100 more, $999, and has a last-gen Core i3 CPU and only 500GB of HDD storage, and, of course the screen in smaller (although it's a full 1080p screen).
