comp.sys.palmtops
(USENET Newsgroup) is my favorite place to get info. I learned a
lot just reading what people asked and posted about the various
units. There are ads here for used equipment.
This is what I use. I have an HP 200LX with a 10MB
PCMCIA flashdisk card and the TechSpeed CPU-speed doubler.
It stores my appointments, diary, shopping lists, CD list, phone list, project info, etc.
(Infomongers keep lots of lists.) It runs DOS 5.0, and reboots using Ctrl-Alt-Del.
It's like my first PC clone, in pocket form. (Yes, eventually I will upgrade, probably to a WinCE device.)
