As a person who has and uses (lightly) a Windows Mobile phone running the Windows 10 beta, I'd love to see it become a/the keyboard option on there. The native keyboard isn't terrible once you learn some of the things it can do, but it still pales in comparison to SwiftKey, and I don't even make full use of the predictive buttons because I'm so used to sweeping.<p>I'll note that in the search / address bar of Firefox, if I type "ne" the three options it predicts are "ne", "news.ycombinator.com", and "news.google.com", where the same entry in a text field gives more expected values.
