I do understand what you are saying and I get what Microsoft are trying to do, but I think if you blur the line between a pussycat and a tiger you could get hurt, same family different habits.
It looks to me like Microsoft have created a (very nice) hammer but now everything
looks like a nail.
in other words is that I don't think you can blur the line that
much and get away with it, I fully expect and look forward to one day (sooner rather than later please) this
when I can put my next HTC/Samsung phone into my dock/KVM and start working away on a full size keyboard/mouse/monitor(s) but I do expect that the OS will be bright enough to realize that it is now a regular computer and adjust its interface to suit.
I don't think there is a one-size-fits-all for computing/mobile computing, we will see and I may be wrong (I was wrong once before in 1982 I think
) but I do think its a massive gamble for microsoft... actually I think its a no-brainer of a balls up but who knows
