I attend
Hey guys! Funny, when I saw the thumbnail, I said to myself, "Dang, that looks just like one of my classes." Then I clicked the link, and realized it was MU.
I can confirm that picture is not staged. Nearly every person at this school has a laptop, and I'd say at least 75% (If not more) are Macs. The school of journalism requires an Apple laptop for the courses. And since we have a very solid computer store on campus, most students purchase their laptops there because of the good prices (Usually student discounted regularly, but includes case, iWork, and 3 years of Applecare).
I'm currently using just a regular Macbook, but that's because I purchased mine before my senior year in HS (I'm a freshman now). I really don't have any journalism specific classes right now. Nevertheless, I'll likely get a MBP after the next refresh.
Even out of the journalism classes, I'd say a good one in three students bring a laptop with them to class.
