I installed the 32bit in virtualbox, its slower then the win7x64 on the same (virtual)pc, and i don't like the "touch screen gadget's" , i think that this could work fine for the new touchscreen smart-phones or similar, but not for desktop pc.
Yes, you can enter the ~win7 desktop~ environment, but...
I only like some of the new features like "reset pc" or something.. that's nice feature.
