I seriously don't get it.  It took me about a half hour using the dev preview and I was comfortable with it.

Which is why I laughed so hard at 'old dogs'

OK, just for grins and giggles.

Running Win7 and Win 8 on the same laptop.

Win 7 gets higher WEI score than does Win 8. Just saying...

I went all in and did an in place upgrade.  Everything still works.  There's a learning curve but once you get used to it it's quicker to use than 7.

I got my SATA and eSATA drive set as a Storage Space pool and that's awesome.  Uninstalled Perfectdisk and cFosSpeed before I dove in, since storage spaces autodefrag, my other disks are SSDs, and the networking is improved over 7.  Uninstalled Adobe Reader for Metro Reader just now.

There're a lot of right click actions that you don't expect at first but once you know where everything is it's fantastic.

Metro is undoubtedly not 'pretty' but it gets everything out of the way so you can focus better on what you're actually doing.

My only gripe is Windows Update...switching from Metro to the Control Panel ver for more information is just silly.  Not really a huge deal but annoying.

I'd check my WEI score but I'm not really concerned.  The drivers aren't final yet so whether it went up or down I'd shrug.

And the game/store apps don't seem to think I'm logged into my WinLive account.  Not a deal breaker but keeping me from viewing the extra apps.

I think everyone would agree that 8 is progress in many ways. Microsoft is constantly adding features and refining things that make Windows more useful, like Storage Spaces. That's a neat idea, although I'm still not sure why you wouldn't simply RAID instead.

What I'm concerned about is that it has two UI's on it and you have to switch all the time. For example, user settings are split between classic Control Panel and Metro PC Settings: some are in one spot and some are in another. It's certainly not unusable but it's quirky in an annoying way.

Where can I get the dual boot tool. I want to run it on my laptop.

Having played with it for a couple of days now, I can definitely say that this when this finally becomes the "mainstream" OS for all new machines, it will be the OS that will finally push me to OSX or Linux.

I see absolutely no benefit to my personal workflow for Window 8, and in fact seems to make it an altogether painful experience to try to get actual work done.
