Wait until August. Best Buy, Office Depot, Office Max, etc. all have "back to school" specials on all brands. Apple has specials that even apply to discounted computers you can buy from the Campus Computer Store https://webstore.hied.com/cgi-bin/We...usComputer.woa
They also sell Dell and HPs at discounted rates.
Mac or PC, you can get some GREAT deals on software too.
Computer choice varies by major -Comm school, Fine Arts, and Education majors lean towards Macs. Engineers are more likely to use PCs. It really is a personal choice though. Most software is available on either platform and there are plenty of computer labs if you ever have to use software you don't have.
