Hello guys, new to macs here. I just got a high end 2011 mbp 15". I still haven't gotten rid of my hp laptop because of microsoft office. I need it to make powerpoints, word documents, excel sheets and etc. I can either.. bootcamp windows 7 on my mac...and not spend any money on windows 7 or microsoft office... but I don't want to have to switch between windows and mac all the time just to use microsoft office. so i might eventually get parallels or something or should i just purchase microsoft office for mac? I only intend to use windows 7 to play starcraft 2. ' what do you guys think i should do?
