I got tired of everything taking so much effort. I was almost always able to eventually wrangle what I wanted out of the OS, but every change I wanted to make and thing I wanted to try needed so much searching and learning. I wanted stuff that just worked, even if it was "dumber."

That, and some parts of the community I ran into were really prickly. One that was especially memorable: I was asking for help on a big-ish project with a lot of followers and helpers and didn't expect the lead dev to answer my question, but when he did, he felt the need to make a snide as hell comment about how I have no business being there if I'm going to forget to start a service. On top of the exhaustion I was already feeling, I had a massive moment of "okay my guy, I guess I'll just fucking leave then."

Anyway, it just feels better being a poweruser on windows. I know enough to keep it clean, safe, and slim (like using powershell to disable the bits they don't expose to a settings UI, for example) -- to truly admin my machine -- without having to work so hard for it day in and day out.
