I don't have any IT yet, but I took my Tapwave Zodiac (PalmOS PDA) and Nintendo DS Lite out in the sun the other day. The Zodiac has a transflective screen and was just as readable outside as inside. Very impressive.

The DS Lite screen, on the other hand, was almost invisible. Does anyone know what type of screen the DS Lite has? If it's the same as the N800 then I would definitely not want an N800.
