I've also been running the beta for a while as a virtual and have the latest build installed.. It's pretty good but personally I won't be upgrading my Win7 machines for a while yet.
Couple of things I don't like (and these are techy type issue..)
You don't have ANY control over installing updates. Microsoft will push them out whenever they want and they will automatically install in the background.
Drivers.. If you have a manufacturers driver installed (the Nvidia is a classic example) and MS has there own version they will uninstall yours and install theirs. This is the "Nvidia issue" as theirs is buggie. If you re-install your own, the next time windows checks for updates... back to the buggie one
Ther is NO indication yet of how much "phone home" stuff is still in the RTM build. The beta was full of it so they could minitor what you're doing.
There are still quite a few other bugs apart fom these that will be addressed as patches.
Lots of stuff is being made available only through the App Store, so you HAVE to have a Microsoft account.
Edge the greatest thing since sliced bread?? Way to early to tell, and I'm a died in the wool Firefox user anyway.
I'll stick with my Win7 for the moment, thank you very much
