Definitely true and I agree with all points. I would wonder how much of the overall laptop-buying population is made up of college students, though? Over time I could definitely see a significant effect (and as is stated elsewhere, Apple is growing much more in that market right now than others), but I would expect that to take upwards of a decade, as you can only 'convert' so many new college students each year.
Given the higher baseline cost of Macs, I would expect them to be more prevalent among college students because a) those people can afford to go to college and b) financial aid makes the difference between a $500 HP and a $1000 MacBook seem much less significant. I am still surprised by that infographic, though: 52% OSX wireless users! I probably would have guessed something more along the lines of 33%.
