I can't remember exactly which language Engadget used, but when they reviewed the Joojoo tablet they talked about the difference in aspect ratio between the Joojoo and iPad.
Basically they said that while the Joojoo's 16:9 (close enough to 16:10) display looked decent, it didn't work well in one's hands. Landscape it was too wide, and in portrait it was too thin.
I care to agree with them. Since iPad has a 4:3 aspect ratio, it's just long enough in portrait, and not too wide in landscape. Sure 16:9 video doesn't look as great as it could be, but I use my iPad more for browsing and such anyway.
In any case, a higher density screen would be nice, but isn't desperately needed in my opinion.
