Backlight: Much nicer than current models. Can't comment too much on screen quality yet until I can get some known graphics into the thing (early unit, doesn't seem to like PENG).

Speed: Perhaps slightly faster than the current Pronto, but once again this is an early unit that I know has a lot of issues. A big help to speed is being able to disable all system animations.

Build: Seems sturdy, but they still haven't recreated the "comfortable to hold" factor of the original Pronto...
