As the title suggests I'm considering upgrading my mid 2007 macbook pro 2.2ghz with 128mb 8600M GT graphics. I'm thinking about either a mac mini or a 13'' macbook pro and was wondering what (if any) difference I would see in performance compared to my current model. At the moment I use my MBP mainly with an external monitor hence my consideration of a mac mini. I've got another ultraportable sony laptop so it doesn't really need to be that portable (if I were to go with a laptop). Anyone got any thoughts?
