I hate it when people BS too. Let's start with your post.
It was mentioned in this thread before: market share does not equal total units sold to date. Steve Jobes probably refers to units sold in the last quarter (Q3 10) or in the first half of 2010, when he sais the iPod touch "outsells Nintendo and Sony portable game players combined".
Let's assume he's talking about the last quarter. According to Technologizer, Nintendo sold 3.15 million DS units and Sony 1.2 million PSP units in the last quarter. So the question is: Did Apple sell 4.4 mio iPod touches or not?
According to
their earnings report, Apple sold 9.4 mio iPods (all models). So the question is: Are 47+% of all iPods sold in the last quarter iPod touches?
I don't know if that's true. And you don't know it neither. But please don't say it's BS if you cannot proof the opposite.
By the way, the average iPod price rose to $164 in the last quarter (from $146 in Q3 09, from $152 in Q3 08). This does not proof anything, but it could be a hint that the iPod touch courrently sells better than we think.
