The gap between touchscreen and keyboard cellphones has just been bridged by the Floating Phone. The Floating Phone is a concept cellphone designed for the year 2015 that makes use of both e-ink technology and an undeveloped technology dubbed the "screenfloat technique."
The screenfloat technique is essentially a way of, in the designer's words, turning a touchscreen phone into a touchable phone. When a user's finger goes to touch the Floating Phone, the screen will raise up ever depending on what function their using. Messaging for example will cause the keys to raise up ever so slightly to replicate the feel of an actual keyboard. Looking at a map will cause the screen to bulge to make the streets easier to see.
The Floating phone has also been designed for use by the blind and features text translated into braille. The hole at the bottom of the mobile is used for cycling through the phone's screens as well as customizing its homescreen.
