Designer Iskander Utebayev did a fantastic job making a concept video that imagines what Apple's forthcoming alternate reality eyeglasses might look like. You put them on, and a monitor-like interface appears before you. This would do away with the need for an LCD display. Utebayev even included a virtual keyboard, which would probably be hard to use for writing a lot of text, but adequate for inserting emoticons, as shown in this short video.
