My old friend who does programming at the highest levels of national governments and classified military applications told me years ago that there is a mathematical proof that software can never be entirely free of bugs. While I don't in any way understand how this calculation might be accomplished, I can certainly accept it on the basis of what I do know and have witnessed. My point is that we can expect software to work very well and to have flaws patched when they're discovered. Assuming carelessness or incompetence in the event of bugs or regressions and being contemptuous when discussing them just shows at best, a lack of technical understanding. OS3 will not likely be perfect but it will be very good and then get even better. We know that because we know Chris.
While I'm quite satisfied with MM, imperfect though it certainly is, I don't think a debate about it is terribly useful since people do have differing opinions and as has been established, it will be replaced. If anyone really wants to persuade me or anyone else to hate MM, have at it but I don't see the point. There are different tastes and different priorities.
