I don’t know if something like this (In-App Sales and iTablet: The Killer Combo to Save Publishing? | Gadget Lab | Wired.com) would work, but I really like something like that to buy and read comics and graphic novels on. If the screen was the same size as a printed comic book page and in colour then I’d be first in line to buy one. (Plus I wouldn’t have to worry about the plastic bags etc. for keeping the comics in).
