Static: Yeah! I guess there are a few of us out there! Haven't seen any detailed reviews on the camera or GPS plug ins for the Prism - but there might be something on ZDNet somewhere ( <A HREF="http://www.zdnet.com" TARGET="_blank">www.zdnet.com</A> ?) A couple of warnings about plug-in cameras: firstly, they're all pretty rudimentary (fixed focus, fixed focal length, only work on nice sunlit scenes), they invariably have no flash (major limitation), and they tend to be heavy on batteries. Also, I'm always a bit leary about gadgets with lots of plug in accessories - you always seem to get into a situation where you need to plug more than one into the same socket at the same time.
Canuck: 6-8 hours does kind of put the Prism in the same league as all the WinCE Pocket PC's - I suspect that what you gain in speed gets traded off for shorter battery life. I'm also in somewhat of a similar dilemna - moving to the Palm IIIc meant that I also moved to rechargeable batteries. And I do wonder just how long they will last on a long trip.
There is a possible solution from Landware <A HREF="http://www.landware.com/catalog/palmos/index" TARGET="_blank">www.landware.com/catalog/palmos/index</A> who offer a battery pack for the Palm V - don't know whether that will work with the Visor of the Palm IIIc - might be worth checking out.
Useful piece of software (also available from Landware) is TakeNote! which is a useful editor that gets around the problem that the Palm can usually only handle documents that are 4Kb in length (longer documents are handled as serial chunks of text). Came free with my GoType! keyboard.
Two other useful sites are <A HREF="http://www.AvantGo.com" TARGET="_blank">www.AvantGo.com</A> which gives you news feeds from various sites every time you hot sync when you're logged on (I think there are some aviation sites there but I haven't tried 'em - PPRune sure isn't there - hint hint Danny?) and <A HREF="http://www.peanutpress.com" TARGET="_blank">www.peanutpress.com</A> from which you can download books - useful for long trips in cattle class. Incidentally, both these sites (and Landware) cater for both Palm and Pocket PC, but not, I think, for Psion.
Enjoy!
