My post's information includes info on the SDCard slot and the ProDUO slot.
From what I can tell, the UI takes up the same amount of space (about 20-30 pixels @ the bottom while reading).
The screen can also be rotated to be 1024x600. It also has a dual-page mode when in the widescreen orientation.
