Hello, my girlfriend is looking into buying her first Mac, mainly for university. She won't be doing anything intensive on it, just word processing, powerpoint, iPhoto, iTunes, Mail, YouTube and general web surfing. Is it worth buying the baseline Mac mini now, or should she wait for the 2013 refresh? She doesn't need it urgently, however, it would be good for her to get used to it. I'm guessing the Haswell chip won't make much of a difference for what she'll be using it for, will it?
