BOAC so is there a good PDA now the Psion has gone
Personally I found the PSION dificult as I never came to grips with the programming language (tempus fugit, I guess) and the programmes available were a bit limited.
I launched into PDAs with a reasonably cheap Ebay second-hand IPAQ 3870 (now well obsolete - Win Pocket PC 2002) and have been overall impressed. I have Sat-nav, Wifi, and bluetooth and just about all my desktop info can go onto it if required. I am 'playing' with Pocket FMS at the moment and it looks good. I use 'Message Manager' with the PDA screen keyboard and bluetooth for SMS via my bluetooth phone and for working on the phone address book. Visual Basic for the Pocket is there for those who need to 'create'. The sync cradle and programme is also easy.
So I am of the opinion that it is the way to go. To answer your q, yes, the 3870 is 'good' - but - there are many drawbacks, like small screen and consequent difficulty navigating the web, limited battery life, etc but the combo of !aaggh! Windows, bluetooth and wifi makes this form of kit, IMO, the way forward.
