I test ReactOS every now and then on a crappy 2011-ish laptop I bought from a thrift store a while ago to test one of my projects on Windows and Linux on real hardware.

Last time was about a month ago. It's still easier to list what works than what doesn't, but I like seeing progress. Ethernet works with some random Windows driver. The integrated GPU doesn't, but installing the driver doesn't make it bsod on startup any more, so that's an improvement. I've seen people have more success with discrete GPUs. Sound card doesn't work because it's too new.

The thing with these kinds of projects that target a vast existing library of software is that the progress feels slow for a long time, but at some point there's enough compatibility for people to try to use it for real, and this is when compatibility starts improving rapidly. I feel like ReactOS is close like never before to that point. I really want it to succeed.
