I found Swype not to my liking, almost useless.
I am not real fast, but my typing method using on-screen boards is with my left index finger, and I do have a steady, rather quick rhythm about it. Swype turned out to save me about three seconds per average short text, and about 6 seconds on longer ones, as long as the texts were not technical in nature, then it failed all together, costing a lot of extra time going back to spell certain important words correctly.
I really don't need those extra seconds in view of the incorrect spellings Swype kept coming up with, in addition to the fact that many words I need to type are from a medical dictionary, which Swype has no clue about at all, given its silly attempts at forming some of those words (some of those attempts were rather amusing).
