I don't know how they're going to make subpixel anti-aliasing work if you can rotate the display. I wouldn't be surprised if they just are re-using the ClearType name and it's not actually sub-pixel anti-aliased, just regular anti-aliased (like the iPad).

The OS knows, at some level, the orientation it's displaying the screen in. So in principle, there's no reason it can't use subpixel rendering appropriately. Although it might be hard to achieve - I don't know how the graphics stack works.

Good point, since most pixels are taller than wide (it'd suck even more if they can't sub-pixel render in portrait mode, as it seems the more natural reading position).
