Android Jelly Bean keyboard ported for Ice Cream Sandwich!

The Day #1 Google I/O Keynote offers a very brief demo, revealing a striking similarity to the 3rd-party application called SwiftKey ...long considered by many the best Android replacement keyboard. Some users say it's better than Apple's IOS keyboard -- high praise, indeed.
