So it will be completely different to the current windows which you want to stick with because "We like windows, it's familiar and works the way we know. We grew up with it."
I completely understand that Microsoft will find a compromise somewhere between a tablet interface and a workstation interface. Their track record makes me think it'll be several releases before it works properly for either and is unlikely to live up to their promise.
However, it will NOT be the windows interface that works the way you know, so you can't use that as a justification. And if you're going to change, you might as well look at all options.
BTW Android is Linux. People have already demonstrated Android devices which convert into a Linux desktop when a keyboard and screen are attached. None of this is new. A few seconds searching found http://www.youtube.com/watch?v=66S8is1E9MI. Or if you've rooted your device, you can just install ubuntu as an app.
