The last time I blogged SwiftKey was in August when it was in its first beta. I was amazed by the speed at which i was typing or not typing because Swiftkey is smart enough to guess my next words and most of the time, if not always, it is spot on. SwiftKey is out of beta and can be purchased for $0.99 on Android Market. It still shows up as a beta for me.
If you haven't tried SwiftKey yet, download it from Android Market. You won't believe how fast you can type.
