I know Apple doesn't make PDAs as of now, but I'm gonna need one soom for clinical rotations and other stuff for school and such (med student), anyways, I've never owned one and I really don't know where else to ask, so do you guys recommend any models? Preferably compatible with mac? (If its any help, I own a MBP). I know PDAs have their own operating system and such, so do you guys own any, and if you do, what do you recommend, etc, thanks for the help.
