I have a new two day old baby, I mean, MacBook. I have partitioned it into two partitions, one for Leopard and one for Vista. Leopard works just perfectly. But Vista... well, that stinking pile of **** is another story altogether. I installed Vista just fine, and used Windows update to get it up to date. I installed just a few additional pieces of software: Microsoft Office 2007, Quake 4, Firefox, Google Talk, Yahoo Messenger and Windows Live Messenger. I then tried to install McAfee Viruscan, and while the install was going on, without warning, I got a blue screen. Hard power off, and boot again into Windows, choosing normal boot and not safe mode. The login screen appears normally. I enter my password and login. Within a few seconds, blue screen again. Repeat again, same result. I could boot into safe mode and try to repair the problem, but the fact is that I don't trust it any more. So I'll have to format and reinstall. Anyways, the moral of the story is that Vista can't hold a candle to Mac OS X.
