As a computer programmer, I can tell you that it certainly is *possible* to produce bug-free software. However, in a system as complex as the Tyros, the chances of doing so are slim. In any event, being that this is not a new OS, chances are that the vast majority of bugs present will never cause any problems. Windows (any flavor) has anywhere between thousands and tens of thousands of bugs, but most of them don't have any ill effects 99.9999% of the time. Enjoy the music.
