Menus on phones blow. It's a pain in the ass to fussily scroll around on a dinky screen and try to remember what has scrolled away that you were interested in, instead of being able to glance across a page.

I sympathize with the PITA of changing printed menus, but that's part of what you pay for. If I go out, I'm not paying for a lunch-counter experience.

E-paper menus would be a pretty good compromise, if they could be made practical.
