How about PIMKI?  I've stuck a PIMKI (repository? Blob? ...?) on my USB
drive and I use it to keep track of notes and stuff.  I don't use a PDA.
If I need something other than my little Moleskine pocket notebook can
easily hold, I use PIMKI.  

For those of you who don't know, PIMKI is a 'Personal Information
Management wiKI'.  It's pretty cool to be able to pop in the drive,
start up pimki.rb and surf to my own local PIM.  

I've tried Palms, Clies, and others.  I find that the combo of Moleskine
and PIMKI is working for me.
