Is the Windows 8 release preview worth downloading?

[dunmerthief]

I see mixed opinions about it online. Some people say it's buggy and unfinished, other people say it's solid and stable. What is the opinion of people on this board? Is it worth downloading to learn the new development platform(metro and WinRT)? Is it worth using as a primary OS for the time being? How is the driver support? Can I install and play games, watch DVD's, etc?

As a developer in need to get familiar with the new features, download it.

But if you are wanting to download it just to use it as an end user, I wouldn't. These copies usually expire at some point in time anyway. I wouldn't go the trouble of reinstalling my PC just for a BETA. I'll go for it once it is RTM.
