portable development -- python for the pda?

[Clark C. Evans]

Hello. I'm going to be doing quite a bit of travel in January and
I'd like to continue to program on-the-road. So, I'm in the market
to buy a PDA with a fullsize (foldable) keyboard. Does anyone have
this sort of setup working? I typically use python and vim, with
postgresql. I don't strictly need postgresql, but having python
run on the PDA would be nice. Any suggestions?

Cheers!
