I know this is a little dangerous, but I'm running it on my desktop at home and its been quite stable. Only had a few issues after the install with the network card not waking up when the rest of the machine woke up. But that seems to have resolved itself.
I spend 90% of my time in desktop mode, so I haven't really bothered too much with the "Metro" apps and features, though the built in search is surprisingly fast. I'm just glad all my games still work.
