"Apple's laptop sales will exceed those of HP/Compaq, IBM, Dell and Gateway combined by 2010"

So, the prediction mentions "laptop sales", but in his grading, he talks about "Apple Macs only have 13% market share", which I would assume means unit market share? Given the profit share vs market share dichotomy seen in smartphones in particular, I'm left wondering if he isn't a bit too harsh on himself here. It seems likely to me that sales-based market share would substantially exeed unit market share for Apple Macs; surely Asymco or some other smart analyst has run the numbers on this?
