Linux

Started with Zorin but had a rough time. I didn't realize until actual months later that my issues were due to a hardware fault and had nothing to do with the OS. By the time I realized, however, I had settled on Mint. I've since tried a handful of distros but always come back to Mint because I'm so used to it now. I do recommend Zorin for its level of polish and apparent desire to simplify the transition for folks coming from Windows.
