Jobs: The PC is a truck. Ballmer: There's a reason they're called 'Mac' trucks.

One of the more interesting exchanges at D8 actually happened across two days as both Steve Jobs and Steve Ballmer were asked about the future of PCs: Jobs compared traditional computers and tablets to cars and trucks by saying most people will eventually only need tablets while some would still need the added utility of a PC, and Ballmer responded directly by saying, "Well, there may be a reason why they call them 'Mac' trucks!" Ballmer snap. When it comes right down to it, though, both CEOs expressed relatively similar visions about the prevalence and importance of multiple computing form factors in the future and mostly differed on semantics -- Ballmer came right out and said he thinks the iPad is actually a PC, and we're pretty sure Jobs thinks it... isn't.
