I never used Windows in my life, but I got an old ThinkPad on eBay a couple months ago that shipped with Windows 11. I didn't have time to set up Linux, so I used it a bit to browse and so on for about a month before I finally got around to wiping it.

It's really unpleasant. Aside from the ads, the battery life made me think I'd gotten a used computer with totally shot battery and I was ready to order a new one. Nope, after finally switching to Linux it lasts almost twice as long, with no special config whatsoever. I also kept getting random crashes requiring a reboot. I thought there might be bad memory or something. Nope, no issues whatsoever since putting Arch on.

Would not recommend.

I did kind of like the splash screen with world photos, I guess.
