I wonder whether you can install the old HTC soft keyboard that has the compact qwerty. Not sure if the screen resolution would be an issue.
But honestly, if you turn on spell correction and xt9, the full qwerty soft keyboard is pretty impressive. Using my thumb, I tap furiously at just approximately where the keys I want are and the words still come out perfectly.
Oh, in case you forget, we also have the best physical keyboard on any mobile device =)
