I just wanted to let you all know about Brighthand.com It is a great website and they have a forum for PDAs: http://discussion.brighthand.com/
I think we're all doing a great job here at allnurses.com of discussing pda's and programs that best suit the nursing profession, however, if you have a technical question that may not be answered here, you may have better luck at Brighthand. There seems to be a lot of "tech heads" on that board who know the ins and outs of the various operating systems and the resources to fix some of the "bugs" we may encounter (i.e. battery display discrepancies, Hot Synching troubles, formatting....).
There are sub forums specific to each operating system. For example, there are discussion boards specifically for the Zire series of Palm and the Tungsten series series (Tungsten C, T3, T5, TX) and so on....
The Brighthand board isn't nearly as active as allnurses.com (of course not!) but there are many general threads to browse where lots of technical (and not so technical) threads have been created.
