Okay, I *do* want to start writing again, and I'm starting this new job, which will entail a one-hour train ride each way.

So... two whole hours a day, potential writing time. The question is, what tools are the best for use on a commuter train?

I was considering an iPad, or some other kind of tablet device. My laptop is too large for this (17"), and pencil and paper aren't terribly useful, since a) it would have to be transcribed anyway, and b) my handwriting sucks even on a rock-solid desk, let alone a swaying train.
