Windows 8 won't be on tablets, though. That's Windows RT, and it won't run Windows programs.In all honesty its just Windows 7 with a tablet UI slapped over it. While I do think its a fantastic option for a tablet, its pretty much pointless for a desktop and is more of a hindrance than an upgrade
The mixups with AERO versus Metro availability and the fact that "Windows 8" is split into two OSes (desktop and tablet) means I'm taking most information I hear with a grain of salt, and I'm waiting for the actual release to even look at it.
After having been through XP, Vista, and 7's launch and seeing all the absolute bullshit people spout and repeat, I've learned it's best to wait until actual release so concrete info can be gathered.
