What don't you like? We've got 10 on an old Dell SFF here (upgraded from 7 coa) and it seems ok. But we only use it for testing.

I use 10 at work and quite like it.

I think I just lost my patience with the Dell stuff installed that was popping up. Albeit not a lot installed but I'm just used to clean Windows installs with no bloat. I'll probably partition and dual boot 10 Pro sometime soon.

Just need to find a desktop environment that handles HiDPI screens nicely. Could do with some granular scaling.

I had to swap in old (& with bad sectors) hdd, format it and clean install 7 pro, then upgraded it to 10 whenever the rc came out. No dell cruft on board.
