[pct-l] Writing on the trail

[Jes Shap]

Say I wanted to write a book while on the trail. Don't worry about the why
or whether that's a reasonable thing to do, this is a technical question:
what is the lightest way to do it electronically?

Typically, I carry a journal or a stack of loose leaf to rough things out,
then I transcribe that into a Wordpress on my android phone. I carry a
stack of extra phone batteries that I either recharge in town or mail home
in exchange for new ones. But that's for updating my blog and I'm thinking
I'll need a real keyboard and more power to write a book. Any thoughts on
how to accomplish this? Maybe just a bounce box with a netbook, then write
by hand and transcribe in town? Or has anyone tried using a bluetooth or
usb keyboard with an ereader? Maybe this would give acceptable, rechargable
battery life that would be light enough to carry all the time.

Any thoughts or suggestions would be much appreciated.
