Can some of you provide a "PDA Newbie" with a list of things to look out for when considering a new PDA at the moment? I'm in the market for one fairly shortly but really don't have a clue where to start - I like the look of the HP "Ipaq" range but don't know how they compare with other brands - good/bad? Also, as far as functionality is concerned - how have things changed in the last few years (what do you use your's for?!). My only experience is a battered old Psion 3a which I used for 6 months or so before it gave up the ghost so I imagine things have changed a fair bit... Any advice greatly received - I need a new toy! K.
