Can anyone recommend a PDA roundabout £120. Must have colour screen and MP3. Really only want to use it as a organiser and to store my many different passwords I need to remember for all the different systems on my PC at work and at home. Realise this amount prob doesn't give much choice but I'm even open to buying second hand/refurb if it means getting a better spec. I've read some reviews for PALM Tunsgten E2 i believe but I'm a bit concerend that you can't replace the battery on this?
