Windows pisses me off. Seems like they zero in on the worst way to do anything, then run with it. Luckily, I only have to deal with a couple machines at work anymore. Everything I personally run is gnu/linux.
I sometimes ask myself why I make my life so complicated by using Linux since lot of stuff is harder, if I buy any piece of hardware I need to make sure it's compatible etc. But then I use Windows for an hour and realize why I use Linux. Modern versions of Windows are such a royal pain to use. They are unintuitive and just terrible all around. The best version of Windows was Windows 2000. Wish they kept that going, and just upgraded under the hood, without touching the user experience.
