At the moment I have 4 (four) Palms active: my main IIIx (at home), a
IIIxe at work (mainly for passwords storage but it also can be used as
a digital camera - it has the PalmPix software installed so it can
drive the PalmPix module - and it can store 50+ pictures at 640x480),
an upgraded Palm Pilot Personal (2 MB RAM, OS 3.0 and in a Fossil case)
and a P. P. Professional (1 MB RAM, OS 2.0).
It is not sustainable to run all of them, of course. The P. P.
Professional is in great condition (it is almost unused) so I should
preserve it. I have no idea if I will continue to use the upgraded Palm
as it is not mechanically compatible with most of add-ons for III
models. Probably I will use it just to impress friends...
