This I view as the only minus of this unit. I've had my Prism for a month now. Had Palm 1000 then III and now Prism. One word only. No problems whatsoever reported by a guy below.
Screen is excellent very eye soothing.
Speed is good. Colors are magnificent. Had a problem with Grffiti but have disapeared since I installed the patch from Handspring. It's a good buy. You will not repent for it.
