In the latest Janus Cycle video he explained how he started carrying an IBM WorkPad c3 around to manage his contacts and appointments. I found that a great idea for people like me that struggle with deciphering their handwriting an hour later.
I've thought of going back to a palm pilot for the same thing. There are tons of Handspring and Palm Pilot Tungsten versions on ebay for under $40.
I believe the Palm T2 and T3 had bluetooth so would be interesting if you could connect the two to keep contacts and appointments off your smartphone. I'm seeing Handspring Treo 650's for under $100 as well.
