I was just today looking at E-inks new 'JustWrite' technology where the screen pixels are activated by a stylus instead of the backing, so writing feels instant (and might be just about instant too). If this tech also has that possibility, then good on them. Edit: though I'm not aware of a product which incorporates it yet, which is a shame. Maybe I'm wrong - research on mobile is hard. What I'd love is a notebook of the stuff that I could write on and save and swap the contents with an open protocol/app. I'd also probably love hacking on the stuff. Make a 'spellbook' for one of my D&D characters where the contents change 'magically'. :)
