It seems to work find for me, but I'm really not liking the 'Metro UI' experience.
Whilst it has an excellent home on Tablet PCs and touch screen computers, it's really not geared to Desktop PCs and Laptops.
My main beef is the lack of a 'use desktop instead of Metro' option so that I can just tick a box and never see Metro again (in other words, disable it) - even an installation choice would be better.
On top of all this, in my role, I support Windows users and to go from supporting them on a Windows 'desktop' to a Windows 8 style 'Metro UI' is going to cause confusion for both us on the helpdesk and for the customer .... on top of not being very 'desktop' friendly, it's definitely not very corporate friendly (or business friendly) from what I can see.
Now, I've never been a massive fan of change to my OS - I complained when Vista came out, I then complained when 7 came out (M$ took out the 'Classic Start Menu' option) but I learnt to adapt how I use my computer and learnt to get on with the UI, however, I really cannot see me getting use to this at all.
I took my laptop in to work and showed the rest of the team Windows 8 Consumer Preview - the one thing that was mentioned was "No way can Microsoft be releasing THAT as a Desktop OS!?!"
I'm going to be looking at alternatives now - I use Linux on one of my older PCs (Ubuntu 10.04 LTS - didn't upgrade as don't like the Unity shell, seems a bit too Metro like

) or maybe I'll stick with Win7.
For the time being, I'm keeping Win8 CP installed so that I can get used to it and work out it's quirks etc. as I'll end up supporting this stinking pile of c**p at some point.
That's the negatives out of the way, now for a couple of positives.
I love how simple it is to install the OS - anybody can install Win8 with ease.
There's a "Windows Refresh" feature, not tried it yet, but if it works as expected, it's a great idea.
I also like the idea of signing in with your "Windows Live" account - by doing so, Hotmail, Messenger and your personal details are all automatically configured - sure it may have some downsides (privacy?) but for some users it's a great way to configure everything all together without too much hassle.
I'm a bit stuck in my ways sometimes, I know, but I like my computer to work around me, no me work around my computer

surely that's how it's supposed to work ??????
