For me it's: * Lack of consistency. Everything looks and acts different, and some DEs in particular are very religious. * Lack of reliability. I can't keep count of how many Linux installs I've killed by doing something as mundane as just running updates. Just no, I need this stuff to work every day. * Religious zealotry. Look, I don't care about the F or O in FOSS to the extent Linux neckbeards demand of me. I use computers to get stuff done, and Windows lets me get stuff done.
