How many of you have installed Windows 8 so far?

I couldn't resist $15 for Windows 8 and so I'm running the full thing, though I was running Win 8 RC for a couple of months before that.

My first impressions weren't very good, the start page was quite painful, full screen apps weren't fun, etc...

However after a while second impressions came along and I got used to it and found it really wasn't that bad, media center loading times being the exception. - must delete... will not accidentally open in again...

After becoming interested on developing for the windows store I've started reading (ok, watching video material) on it and have learnt a lot that I didn't know before. Now I'm actually rather impressed and am not as sure the MS is heading to their demise as I was before.

What's your experiences/impressions of Windows 8?
