What I really want is a good justification, i.e. excuse to cough up the money.

While we're at it, what's the difference, if any, between a "PDA" and a "PocketPC"?

To get things started:
I'm primarily interested (see other thread here) in using one with a GPS for marine navigation.

Other possibilities:
Play MP3s?
as data bank/calendar/scheduler
as Cell phone?
as digital camera?
to play games on while waiting in lines
to carry files around, e.g. from home to office like a briefcase

Have fun, DaveBo
