It's also important to recognize that Microsoft's investment in Kinect/Netal isn't solely about games; there's a significant component to their Xbox strategy that revolves around non-gaming applications
Will Kinect be cool for video games? Maybe, maybe not. The more interesting question, to me, is, "Will Kinect challenge the entire idea of the 'remote control' for electronic devices?"
Only time will tell.
The developers of Linux decided long ago they like things the way they are, the world could do it their way or go jump
That's entirely backwards. It's Windows that you have to do it their way, not Linux. With Linux you have a choice of distros, desktops, boot loaders, everything. I had a discussion with a fellow slashdotter the other day about how much I liked the way KDE opens with the apps open that were open, with the book I was reading open to the same page it was on when I shut it down, and he hated that. His is configured to open with a "clean" desktop. His is the way he wants, mine is the way I want, and we're both happy. Not so with Windows. With Windows, it's the Microsoft way and if you don't like it, tough shit.
You missed his point. His point is that end-users don't want a choice of distros, desktops, etc. They want to press "on" and have it work. This is, ostensibly, what Windows provides.
A complex system that works is invariably found to have evolved from a simple system that works.
