I'd guess it's a tad faster, after using it for a week in a Dual Boot without going back to 7 yet.
But the Metro mess is a hurdle to get over to the desktop experience. The trial apps are a bungled mess which I ended up having to uninstall since they wouldn't close and ended up popping up as an thumbnail whenever I reached for my browser back button - didn't know then you can rightclick them there to Close, but why there? They seem more like a flashy feature one would want on a tablet which is not browser-centric as is the typical desktop experience.
Once I tamed the Start screen and learn to toggle it I don't even use it except to get to my Programs, with the same one-click to get to 7 Start Menu so that's OK. I just noticed yesterday the right-side pop out with Settings and other tools. It would be nice to have an orientation on all this at first boot after install - that's a flashy app I'd appreciate.
