Hello. My son is interested in purchasing a 20" inch iMac. He is just a regular high school student, and doesn't do much photo editing, or anything like that. I was wondering if buying a Mac for him would be a right idea. I was told macs are only for art students and can't run microsoft word. Can someone give some advice? and also do u suggest we wait to buy in October when Leopord comes out? thanks alot.
