For my new MBP 15 I have 2 choices. I can either get from my college Office 2008 legally for free because it has many licenses. But there is also the new Office 2011 but I will need to buy it. Are there such big differences? I looked at Pages briefly but was not impressed. I mainly use my mbp for academic stuff, writing, pictures, internet, downloading files sent from a variety of PCs and Macs.
