"battery lasts a couple of days..." I think we're conditioned to have a low bar. I want something that lasts a long as that $20 feature phone that I can pickup near the checkout line at Fry's. I want it to be $20. I want to be able to drop it repeatedly. I read somewhere that given Apple's design esthetic, the iPhone will evolve to a slab of glass. It would look like a piece of art. Sounds right. Something with no holes. You can submerge in water. Screen would be all around, front, back, sides.
