First of all, let me say that this was a great idea (Jean, et al). It's been a lot of fun seeing the entries and the discussion it has spawned. I don't think there can be any doubt that Fitaly(Stamp) is the fastest text entry option available for the Palm - bar none.
One interesting note... there've been a number of comments here and there about whether this is a "real world" sample that is valid for time comparisons. Just on a whim, I decided to try the DP test with my GoType Pro. My best score so far (with FitalyStamp) was 56.67 wpm. After 4 attempts with the GoType, my best score was 94.97 wpm. I guess I should make it clear here that I do not type 95 wpm in the "real world." So while the test is certainly valid enough for comparing relative speeds between methods, I would hardly consider it representative of what people can actually achieve in normal typing/tapping/Graffiti'ing/etc.
