the desktop will die
The idea of having "a desktop computer" is gradually disappearing. Your computer workspace will exist on a server somewhere, and you will access it using a terminal-like device, whether that is a tablet or a dumb-screen on your desk at work, or whatever.
Microsoft is doing whatever it can to delay this inevitable trend, while at the same time clawing at whatever market share it can get in the new world.
We're probably only a year or two away from the day when that 22" Samsung you buy at Big Box will have not only VGA/DVI inputs, but also Ethernet and USB ports. COMPUTER OPTIONAL -- if you don't need the headache of a desktop pc, you just plug it into your network, attach a keyboard and mouse, and away you go with a built-in Android OS running on an embedded chip that will cost $5 in quantity.
In this world, your "Windows(R) License(TM)" will be on a virtual server somewhere, whether Microsoft(R) likes it or not. And from there it's only a few steps further until people finally start to see that they don't really need the Windows after all.
I hope to piss on Bill Gates' grave someday.
