It was the Windows XP upgrade debacle for me. That was a bridge too far. I lost the ability to use critical hardware with (at the time) no ability to obtain updated drivers. I went to the local big-box computer store to browse the Apple section. When I saw the price tags I thought, “Oh well. Mac ain’t it.” On my way back up to the front of the store I stopped by the operating systems shelf and stumbled upon boxed Red Hat and SUSE Linux distros. I can’t remember which one I purchased first (I believe Red Hat), but I eventually acquired both. Long story short, I spent several years going back and forth between Linux and Windows while hanging on for dear life while riding the learning curve. I eventually decided to go full-time Linux around 15 or so years ago and have not looked back. Over time I also developed other key concerns that kept me away from Windows, a few of which were security/privacy and the open nature of Linux (to do what I wanted to do with my OS and interface). My most recent computer is a gaming laptop that has two hard drive slots, so I dual-boot Linux and Windows. I keep Windows mainly to perform firmware updates that can be touch and go in Linux (and some gaming, but very seldom).
