I also do beta testing, mostly for microsoft products, when they open the testing up to Partners. I ran first release Vista and Win7 betas on a production system (fully backed up but it's not a real test unless you stress it), tested both versions of Windows Home server, and, for dessert, a couple of games.

I, too, have never seen a BSOD since XP, and rarely on that. That includes my parent's systems as well My Niece is another story, but she was in High School and got Virus infections every other day from so-called "Social Networking".

I've worked on Macs for friends, would never buy one because of the extortion charged for basically the same hardware running Windows, but would entertain the idea of purchasing MacOS as a second OS simply because I was a Unix Admin when Windows was still competing with Digital Research's GEM as a GUI. MacOS would join my library, where I also have several versions of Linux and Solaris 10.

I find it absolutely hilarious that Macs run an OS that was designed for true multi-user functionality, including the ablility to easily stop a crashed process without affecting other users, yet has been obfuscated to the point where the average user has to reboot the machine.

At the same time, Windows, while still remaining single user by nature, has steadily become more "Unix-like" in terms of requiring fewer and fewer reboots with every version.
