Well after an evening playing around with it, I'm more glad than ever that I'm basically a Mac fanboi!!
It installed and runs fine on my Acer Core i3-370M laptop w/4GB ram, but the UI is horrible for a desktop OS. Might work fine on a tablet though. I used to have an HP Touchsmart desktop and found that while touch works on a desktop, it isn't of much value for most apps, and in fact is very frustrating because the touch accuracy just isn't good enough for the desktop app icons and such. The few touch apps that came with that were a mixed bag, some great (recipe app), most just ho-hum.
First issue with Win8 was trying to figure out how the hell to shut it down! 2nd and biggest issue was how to not use the Metro UI! The first was easy enough, the second can't be done as far as I can see.
The simplicity of the metro UI reminds me of MS Bob...
