In fairness, we're talking of three different areas here, though. One's a phone (sort of), one's a tablet-gizmo-thing and one's a (proper)* computer. I can't see the impact of one against the other as most people will probably have an example of each (not necessarily Apple solutions).
It would be interesting to see how Mac sales have done against 'normal' PC sales as I can imagine both markets will be climbing at the mo.
*By 'proper' I mean an actual desktop or laptop regardless of type, so please stand-down anti-Apple-fanboitards!!
