Electronic stuff is neat to own, but how do you keep it from being stolen while you're in the market replenishing your food stuffs? How do you keep it dry?
My handlebar bag goes with me everywhere regardless and is waterproof so neither of these are concerns.
I agree that less is more, but... I am starting to shift more toward using some lightweight electronics in lieu of paper. It is getting to the point where taking an ipod shuffle with audio books and something like a Nokia N800 can be less weight and bulk than a paper notebook, pencil, and a paperback to read. I spec'ed out both ways and come up lighter with the ipod and N800 even including all the associated chargers and so on. My thinking now favors using electronics over paper even more if your cell phone is email capable like for example a black berry. Emails to home can easily serve as your notes and journal entries. I prefer not to pay for data service on my cell though.
I don't want to carry even a mini laptop though. Still, I can see how others might choose to given how small and light they are becoming.
