A usability testing firm, User Centeric, did report the issues surrounding touch screen keyboards, specifically regarding the iPhone. Their empirical study results were reported at a New Jersey Usabilty Professional Association presentation last year. Here's a link to their website discussing their results comparing hardkey vs. iPhone's softkey error rates.
http://www.usercentric.com/about/news_item.php?m_id=4&s_id=4&q_id=4&id=15&year=2007 I have been using a Blackberry Storm for a few weeks now. I would agree with previous remarks about the touch screen keyboard performance as well as the errors. Some delays in response time from the touch screen keys and buttons can be annoying. There is a learning curve and you are forced to type slower (when doing a speed/accuracy tradeoff). I had a hard time figuring out how to "hide" the keyboard because there was no explicit button that I could easily locate using the touch screen until I discovered by accident a gesture that would "hide" the keyboard. It may be documented somewhere but I'll have to admit that I tend not to read the documentation unless it is absolutely necessary. I did find out about another touch screen smart phone by Samsung Omnia that improved upon the other designs by having an explicit hide button for the keyboard was well. The keyboard "buzzes" after each key press as a feedback mechanism. I have no association with sales, servicing, development or evaluation of these products.
