I really enjoyed Swype early on, but I never figured out what their plan for it was - it seemed to be in perpetual beta, when I'd have happily been paying for it as an app. The weird installer shenanigans and insistence on internet access finally killed it for me, well before them getting acquired.

It's sad in a way - I also thought it'd be on every phone, but it looks now like that's more likely to happen via the same functionality being built into other keyboards rather than Swype doing it themselves.
