The Minuum Keyboard
 

"The Minuum keyboard, through its simplicity, improves your touchscreen typing. Existing keyboards leave you barely enough screen to interact with your apps, and you can't enjoy typing on them. Minuum eliminates the visual clutter of archaic mobile keyboards by adapting the keyboard to a single dimension." You have to watch the video. This is yet another example of a strength of more open platforms - like Android - that often gets overlooked: the ability to experiment with core aspects of the operating system. Whenever someone says there are no Android-exclusive applications, they conveniently overlook things like this. No other platform has stuff like this, and I certainly miss this experimentation on my 8X.
