It needs a lot of work. For example when I try to view a video that is in a link to Vimeo, I get a pop up block dialog even though I have put Vimeo's URL in the exception window. So I have to reauthorize popups from Vimeo each time. Then when I get to Vimeo on the second try there are no controls to play the video. I've participated in these preliminary user programs with each new version of Windows since Windows 95. Windows 8 is the least useable of them all. This doesn't reflect well upon Microsoft (and I'm not even getting into the fact that many features of Windows 7 have been changed to make them more difficult to use). Another problem is that my USB wireless adapter connects to the router upon booting into Windows 8 but then immediately disconnects. I have to manually connect to the router each time I boot into Windows 8 even though it is set to automatically connect. So I'm going back to Windows 7. Perhaps when Microsoft releases Windows 8 I'll take another look at it. But I'm not expecting miracles from Microsoft.
