Honestly, a laptop or even a tablet PC is probably more practical. Pocket PC's or Palm's just aren't too practical for the things you're describing. I guess it may be better with a keyboard but you're still stuck with the limited size of the screen.
There is voice recognition software available. You probably could find something on www.handango.com and searching a little bit. But considering that voice recognition software on the PC is pretty iffy, I doubt you'll find anything very reliable on a PPC.
But if you're bent on getting a handheld, pretty much get anything $200 or more. Since the OS's are the same, there's really not much of a difference between a $200 and an $800 handheld. At least in terms of holding addresses and typing stuff. Obviously, more expensive handhelds have faster processors, extra features like built in cameras and keyboards (Sony Clie's), and wireless support (bluetooth and wifi).
I'm studying abroad next year, and wont have a computer in my dorm. I need something to type my reports and etc on, something to keep adresses in, becuase I wont know my way around, and some voice recording capability for things I dont have time to scribble in.
For that matter, is it crzy hard to type a term paper on a handheld? Even ifit has a keyboard as apposed to graffiti?
Is ther any voice recognition software for handhelds that could make life easier for me?
