SlideIT Keyboard: Performance

Overview
The basic idea behind SlideIT Keyboard is fairly simple. Instead of tapping keys individually, you slide your fingertip from one letter to the next. While it uses a full keyboard, SlideIT does qualify as a form of "predictive input," because it's making assumptions about what you mean to type. You can't slide your finger from "e" to "e" when writing "guarantee," for instance. So it guesses that that's what you meant to type when it gets "guarante" from you.

The most famous input system along these lines is Swype. But Swype is only available pre-installed on some devices, not for sale via Google Play (the download site previously known as Android Market). This gives SlideIT a major advantage over the alternative.

Aside from predictive input, SlideIT also offers some extra features such as speech-to-text and handwriting recognition functionality.

The app comes in two flavors. The full version costs $7, whereas the "free" version is a demo only good for up to 15 days. After that, you've got to either give it up or fork over the money.
