update::
programming on a palm device is insanely annoying when you have to type in significant amounts of code. So initial generation is out, but i've found that debugging is actually quite pleasant and simple. You write or download your code to the palm pilot as a .pdb, load it into pippy(a palm IDLE equivalent) and spend some time sitting under a tree in a park, or lazed out on the sofa, or in a restaurant/cafe formatting, organizing and correcting the code.

It's really upped my enthusiasm for debugging, which is generally low.
