One of those netbooks with an LED monitor that hinges in the middle... That would be nifty. They're running 1024x600, and having one fold so it was 1024x1200 or so would be sweet. The LED displays are very thin so stacking a second monitor on top of the first would add maybe 1/4 inch to the total thickness. Power consumption would increase of course, but I think a lot of people would be willing to giv up 30 min of use to get double the vertical screen size. It would end up about the size of a regular piece of paper, which is plenty large enough to do real work on.
