Nah, been there, done that. I don't feel like alpha-testing the OS for free. If I install the OS on a VM it's useless cause I would only fire it up to run potentially malware/unsafe apps, so there's just the main PC left, which I want 100% stable. I really, really don't want BSODs. I hate them. You can never tell with certainty if it's your PC dying on you or just your alpha OS, so there's no real troubleshooting cause you can't troubleshoot when the very basis, i.e. the OS, is proudly and openly unstable. Then there's also the drivers which might not like the new build, hell no, not gonna deal with that.
