About two years ago, we asked you the same question we're asking today. But two years ago is a long, long time in Android terms. A lot has changed in that time, and there are substantially more software keyboards to choose from (respectable ones, at least) than there were then. At least, I think so.
SwiftKey is likely still the most popular third-party keyboard on Android, that much we can probably assume, but I have to wonder: how much headway have Google, Swype, GO, Fleksy, and others made in the last two years?
