I have the 64bit iso waiting till I have the few moments of interest to fire up a virtual machine and give it a try.

The main problem is a WDDM reliance of the new windows. However a full HVM (with PCI passthrough) can get this working fine.

Imo metro styled start menu + aero interface = epic fail.

I'm a bit discouraged by Metro, actually.  Navigation requires unnecessary clicking and dragging on a conventional PC without a touchpad that supports multi touch and gestures.  It seems like a lot more thought is going to need to be put into building a universal interface to handle to differences in usage models between touchscreens and conventional hardware UNLESS next year brings about more touch interface computing platforms and drives the nails into the coffin of how we currently interact with our computing hardware.  MS has stated that their current goal is to build a single OS that spans a wide range of computing usage models...one OS to bring them all and in the darkness bind them.  It's too early to tell since 8 isn't even in beta yet, but I'm not so sure this is the right path moving forward.  Perhaps using the same core OS makes sense, but vastly different means of interacting really do deserve a UI optimized for their unique advantages.  Given the fact that quite a few people who own tablets (including myself) use them mostly as an expensive means of collecting dust, I'm not sure the way forward is in tablet technologies.  Perhaps ARM processors have a place in the coming new order, but I have my doubts about tablets when phones are already able to do everything a tablet can and most of what a conventional computer could though on a more cramped screen.  Dock those things to a larger screen, keyboard, and touchpad with a beefy battery or just a touchscreen and the whole point of a tablet evaporates away.

On a side note, my ancient D620 with its pathetic Intel GMA 950 integrated graphics card tosses 8 around with little trouble.  Microsoft is living up to one of their other goals in keeping system requirements quite reasonable.  It's a pity that MMO developers don't also acknowledge the lowly 950 so I can keep playing things like Perp.

In time all interfaces will need to be covered in a proper way, but if one wants to use all of them, you have to start somewhere. Maybe microsoft is the new apple ?:D
