It's hard to say what Steve meant by "laptop sales". I'm assuming that your interpretation (unit sales) is probably correct and Apple is definitely not that large. Their growth is certainly outpacing the industry, so maybe Steve is off in timing, but Apple doesn't keep on the low end which makes it harder to build up unit volume.
Even by revenue metrics, I doubt that Apple is bigger than all of those brands combined.
The thing is that Apple seems to maximize on profit (silly folks, they should know that market share is what you're going for). I couldn't find the figures, but I'd be curious to see what percentage of laptop profits belong to Apple. In the case of mobile phones, Apple now gets 60% of the profit in the industry.
