I have it dual-booted on my SP3 (i5, 8GB) and I'm not crazy about the current build. The battery life is horrible, and it runs hot all the time, even while only doing basic things like web browsing. I still boot into 8.1 about 99% of the time, and even the times that I do boot into 10, I can't be in it for more than 5-10 minutes before I get annoyed by the fan running on full blast. As far as functionality and tablet usability goes, this build is great compared to the older builds, but there's still a lot of work left to be done before I'd consider it for my primary OS.
tl;dr version: I wouldn't recommend it for now.
