I suspect the source of reports like robin's is the common (and misguided) perception that a few buggy things indicate an overall bad experience. Highly selective use often exacerbates that perception, whereas certain exclusive use can produce the opposite. For instance, I have not used the thumbboard in months so I have not seen any bugs related to it. In fact as of today after installing 51-3 the only significant problem I've seen is Maps crashing (at very bad times too). Other than that and some occasional poor responsiveness from microb OS2008 is running very nicely for me. I don't say that to make robin or anyone else feel bad, but to offer additional perspective. That actually can help in troubleshooting.
