First of all, thanks for your help. I plan on upgrading my late 2010 MB to a MPB in the next few years but I had a question that will greatly effect my decision to change. I know apple does some things with transferring your files when you buy a new computer, but will they also transfer my installations? For example, I borrowed a friend's copy of Office '11 Mac. I can't borrow it again, but when I upgrade computers will this installation go with it? Thanks.
