I got it fully installed this weekend... I definitely like it. Seems to be very quick and obviously aesthetically pleasing. Seems to have combined a lot of great Windows 7 stuff with Windows 8 stuff... rather than throw the baby out with the bath water, which is what Windows 8 kind of did.
Definitely had some initial bugs. Of all the drivers to experience issues with the upgrade, of course it has to be the WiFi adapter. But once I got through that it was mostly OK. For a while there, when the PC booted, it would go to a blank screen rather than the log-in screen. Oddly enough, when I would go to power off my computer, the screen would somehow magically appear. It's not been doing that the past couple days though, so hopefully whatever that was, we're out of the weeds. Super annoying, and weird.
