I used Windows since my first PC on 3.1. But recently it just became too much. Switched over to Mint for just over a year now and loving it. No issues at all for development or gaming. The machine just works. No lag at the lock screen, typing in your password and hitting enter has the desktop loaded instantly. It just works the way you expect and with the performance you expect. I used to defend Windows but I cannot say the same about it anymore.
