Okay, here's my novel. :)
First, look at the battery. You want a lithium ion battery -- that's the kind you can charge a lot without hurting the battery. I have a couple of friends who have PDA's that run on AA's, and they never have the PDA with them because they need new batteries. It's not much use if it's not with you
24/7.
As to operating system, it's pretty much shaken out that Palm OS and Pocket PC are the big contenders. If you want to work with a Mac, you need Palm OS, otherwise you can go either way. More programs are available for Palm OS, but Pocket PC is catching up fast. If you go with a Palm OS platform and you're sync'ing with a PC, you can use Palm's software (which is free) or you can sync up directly with Outlook, which is what I'm doing. You can also sync multiple computers -- I sync to two computers at work and one at home so my schedule is readily available to DH and employees, and they can leave me notes at any of those places.
I'd recommend at least 8 Mb of memory, but if you can pick up a 16 Mb system for not much more, go for it. I've used 11 Mb of 16 on my Handspring (Palm OS), but I have some big memory hogs -- 2 weeks of TV schedules take up over
2 Mb, and my genealogy database takes up another 1.5 Mb. Plus a number of games, err, mental stimulation programs, yeah, that's it. :)
To get an idea of everything you can do with a PDA, take a look at
formatting link
(NAYY). I checked that site out when DH wasinitially making noises about getting himself a PDA, and it convinced methat there was
*nothing* I couldn't do with a PDA. So I went out thatmorning and bought one for myself. :) Is there one model you're looking at in particular? I'd be glad to give you my opinion.
