Yup. Boot time and loading of system apps. 8.1 was basically instant while XP and Mint had slight delay. Not a big deal though, just something interesting for being Windows. After all, it was made for tablets.

I also put Windows 11 on it despite being unsupported. That was slower, but still OK-ish with SSD. Definitely nowhere near Linux Mint though. The background processes were just killing the CPU. Thankfully, thanks to being made in 2007 the cooler could easily take 100% CPU usage. However, it would hover around just 6% with network disconnected. Hmmm...
The CPU was Core 2 Duo T7500 upgraded from T7100. I got it on AliExpress for €1. It seems some people were using them for... making keychains? Anyway, they were sold as functional.

I wish laptop CPUs and GPUs were still upgradable. The GPU was GeForce 8600M.
