Sorry, I've decided to give up on Keypurr. I just can't type reliably with two thumbs. The biggest problem is with the keys around the space bar -- I'm always hitting space when I want an "n" or the period key when I want a space. I'm going back to SlideIt or Swype: my index finger is much more dextrous than my thumbs, and holding the phone firmly in one hand while tracing with the other is much more comfortable than cradling the phone in my fingers and arching my thumbs over the screen (not to mention the fact that I'm much less likely to drop it). No knock intended on Keypurr -- I'm sure it's great for people who were already typing that way with some degree of success -- but it's not a "keeper" for me. I will mention in parting one issue that occasionally happened with me. I have a Nexus One, and I imagine the problem has something to do with the idiosyncrasies of that particular digitizer, but it occasionally happened that I would slide up on a key and get the lower symbol instead of the upper (e.g., slide up on "s" and get "6" instead of "a"). When it did happen, I could do it several times in a row, and sliding down would give me the upper symbol.
