I actually quite like Windows 11. It feels like Windows 10 with a lot less strange, incomplete and broken features. Having more options for window-tiling especially on my multi-monitor setup are a godsend, and miles ahead of the same system in 10 which in addition to not having the aforementioned additional options, also just kind of broke a lot and didn't work correctly.
Additionally I like the Mac Dock-esque revamp for the taskbar, and though it still has an annoying number of UI conventions that one snakes through like exploring the layers of Aperture labs, the new ones are actually quite nice, very usable, and don't feel like simply a barrier I must pass to access the settings I actually want.
My sole beef is that changing audio outputs now takes four clicks instead of three as they buried that button next to the volume control in whatever they're calling Command Center. But that's not a huge issue.
It wasn't a massive upgrade to be sure, but it was the first Windows release in awhile where it felt like an overall improvement to the experience across the board. Everything is a little shinier, a little better done, a little polished, etc. I wish more were like it.
Edit: Cohesive, that's the word I was looking for. It feels much more cohesive than 10, or really any of them since like 7. It feels like something that was actually designed for purpose, not just a mashing together of the various outputs of various departments.
