Re: We have a winner
"..[The PC] remains the best tool for an awful lot of jobs."
I suspect you mean, "monitor, keyboard and mouse remain the best tool for an awful lot of jobs."
It's becoming irrelevant where the CPUs are: it could be they're in your mobile phone wirelessly connected to a dock, it could be they're on the other end of a network connection or it could be they're in a box on, or under, your desk. If you want to convince me there's a future for the PC you need to convince me the box on the desk is better placed that the box in your pocket or the box in the datacentre. (And remember, cheapest normally wins out over best engineered or most usable.)
