> It's a bizarre method of text entry, but interesting nonetheless.

And by bizarre you mean fantastic... It's even better in a language like French, where swiping means not having to type in the accents, whereas normally you'd have to do a long press of the letter and then select the accent you want...

You don't need to type spaces either and keyboards can be more compact as it's about the word shape rather than hitting a particular letter sequence exactly. Stock Android 4.1 version at least seems pretty forgiving provided I hit the correct first letter, a lot of weight in the algo appears to lie with first letter.
