Fraser Speirs provides an excellent explanation for what smartphones, tables and PCs are good for:

I’d like to propose that we can look at the ‘sweet spot’ for each type of device along two axes: task complexity and task duration. Task duration is the more obvious of the two: how long of a continuous period will you be using your device for the task.

It really is an excellent way to think about it in a way that’s much more systematic (and accurate) than “smartphones and tablets are for consumption, PCs are for work.” He argues, based on this explanation, that a larger iPad could allow iOS to encroach further into the PC’s territory. He’s absolutely right, but it wouldn’t be easy; to take full advantage of the screen size, applications would have to be designed specifically for the larger screen—which could result in fragmentation among “iPad” applications. That wouldn’t necessarily be a bad thing, of course, but would complicate the ecosystem.
