I tried it while it was in beta. It's not yet ideal but definitely on a good path to compete for the default keyboard replacement for Android. It's especially useful if you tweet a lot from your phone and need to precisely cut and copy single words and sentences. Beats the Android defaults by far. The usability and the speed of the app needs to improve, though.

needs some improvements. choice between having keyboard with nice cursor control and lack of autocompletion/language select (can not use non English spellchecker) or numerical keypad and keyboard with this features but broken navigation is hard.
