Because I have a fantastic sense of timing, it turns out SwiftKey left beta today and is in the app store: https://play.google.com/store/apps/details?id=com.touchtype.swiftkey The trial version for phones is here: https://play.google.com/store/apps/details?id=com.touchtype.swiftkey.phone.trial I have written about SwiftKey extensively in the past. Suffice it to say, I highly recommend it. It is hands down the best keyboard, soft or hard. The new version has undock and split modes for phones as well, and an option to shrink the keyboard to corner, allowing one handed typing for phablets (the Note has this function, but it only works with the default keyboard). SwiftKey has a flow mode like Swype, so the compact keyboard mode would make it much easier to slide your thumb around one handed even on less enormous phones like the 5" Galaxy S4.
