I got it a couple days ago. Took about an hour+ to download and install. Coming from Win7, It's certainly different. It looks and functions like a tablet. Meh. Not really my thing. Supposedly, they give you 30 days to revert back to whatever you had previously. There's been some problems with video playing correctly. It doesn't seem to want to play one of my programs, KodiTV--yet. I read that there will be intermittent bugs until they roll all the updates, which they doing slowly, incrementally, but the foundation is there.
Interesting thing I read..they are likely not going to produce another OS. This is it. Meaning, I guess, they will update it live as a background process, like the way google chromebooks are updated. You won't ever know it. It'll just be done when you power up.
