Ben Thompson has a good post about the differences between “computing” tasks on the Mac and the general-purpose nature of the iPad. I agree with his conclusion:

Ultimately, it is the iPad that is in fact general purpose. It does lots of things in an approachable way, albeit not as well as something that is built specifically for the task at hand. The Mac or PC, on the other hand, is a specialized device, best compared to the grand piano in the living room: unrivaled in the hands of a master, and increasingly ignored by everyone else.

Forget about this stuff and forget about “convergence”. My question is: for the future, does Apple think that the iPad – and by extension, iOS – will become suitable for traditional computing tasks?

Right now, Apple’s answer is that the Mac and iPad can coexist, each in a different space – and I believe that’s accurate. But as more people will choose tablets and smartphones as their primary computers in the coming years (with Mac sales further shrinking alongside the rest of the PC industry), will they start wondering whether spreadsheets, layouts, and photo management can be done on a multitouch display?

Does Apple think that their customers will want more from the iPad? And how would they deliver more without making the iPad more complex and less “magical”?
