Disagree -- if Apple goes 3x3 like they did with the new iMac, the increase in throughput on ac will be a boon to those of us that move large files over wireless.
My son is at Virginia Tech in engineering. They are required to have a Windows laptop, down to specific models and specific software suites. If that were not the case, he'd still be on the MBP I passed to him at the end of his junior year in high school to get "used to" before he hit college.
Checked on the KU Bookstore's website. Engineering majors can have macs, but they need to be able to dual boot into Windows. They also need a minimum of 4gb of RAM. Wouldn't be surprised if that changes in the next year or two.
I'm a history major, so all I need is base specs (i5, 8gb ram since you can't really get 4 anymore) except for drive space. I've already invested in Office for Mac, so it seems silly to buy a PC and related software when I graduate in 7 months (cue panic mode!!).
