This became my default position after years of misguided Linux activism, which was partly philosophical zealotry and partly a desire to avoid becoming tech support for yet another one of those horrid Windows machines with their choked system trays and their dubious antivirus packages. Eventually I just started telling people "You can have free unlimited tech support from me if you let me put Linux on it. If you insist on Windows, that's your choice, and I wish you all the best, and don't come crying to me when it breaks, which it will". Made my life much less stressful.
