Yes i started collecting those not so long ago, mainly because they are plentiful and really cheap :

Didn't liked the III series in the first place (mainly because they are huge compared with the V series) but are easy to work at (V's are glued) and powered by batteries (except for the IIIc)

I also collected a Palm Pilot and a Psion 5 (really cute machine)

this morning i left behind a Palm V (not The Vx just the first model) it was just 3 € but was missing the stylus and charging/sync station...and i already have 3 V's !!

No Apple stuff unfortunately was found this morning.
