Ok, so I'm sure that the differences have been discussed between these two things a lot but I have a couple of specific questions regarding the differences. 1) What is the price difference? I am a college student so I would probably be able to buy them for fairly cheap at my university. Around how much would they be? and I heard something about getting office 04 then buying an upgrade to 08 for 10 bucks? So what exactly is the deal with that? 2) I will probably have to be transferring some documents from my mac to pc's back and forth. Which one would be better at doing this? Thanks!
