How is the onscreen keyboard on the tp2?

[tokuzumi]

I know the tp2 has a nice slide out keyboard, but there are times when I'm using my mogul that I wish I had a better onscreen keyboard to use in portrait mode (meaning not having to use the stylus). Just curious to see what your opinions are of how quick you can type on the keyboard, if using it causes too many typos, and if the auto correction works fairly well with the onscreen keyboard.
