iPads are "family things" where kids play games and when they go to bed parents get to use. I can understand buying an iPad so my child can play angry birds and watch movies.
I DON'T see why any college age kid needs a quad-core maxed out 15" rMBP to write papers and take notes in class. And yes I understand that you don't have to be in college to spill beer on your laptop but I'm saying the average college kid is more likely to be careless about stuff like that. Again this is just my opinion but I think the Macbook Airs are much more friendly to the college population. I just think the 15" rMBP is overkill for most college students.
As student I never broke/lost anything like that, was just fine. - Whilst I didn't need a Mac (or want one at the time) I just needed something powerful enough to run CAD software so I built a PC myself.
I still don't think you need a laptop in college, better off getting an ipad/tablet with a dock-able keyboard - it's over kill to drag around all day.
But if you have parents that are willing to spend silly money on an over specced laptops you - so be it. I'm sure their very happy, I wouldn't of appreciated it at that age anyway.
I just hope theres a price drop along with the refresh (if theres any update at all this year!)
