The greatest feature of this keyboard is the word prediction that it offers, with sites like Androidcentral's Jerry Hildenbrand, saying "I'm one of SwiftKey's biggest fans". The keyboard even had a record of 100,000 download just a few days after release.
SwiftKey offers intelligent next-word prediction by analysing the context of a user’s sentence and input behaviour. This is accomplished through TouchType's Fluency™ prediction engine, which employs statistical language models generated by analysing billions of words of background text.
In our tests, around a third of next words are correctly predicted without any characters being entered and roughly 80% are predicted within two or fewer character prompts.

If your interested, it is now available in the market for less than $1, which is great pricing for what you will get.
