Getting a new computer within the next couple weeks. Can't decide on the 15 inch i7 macbook pro using external memory as well, or the 27' iMac with the i5 processor. I have a laptop right now that i would like to sell if i were to get the macbook. so basically will the macbook pro preform as well as an imac for video editing? and if not how much better is the iMac? the specs look fairly similar to me besides the harddrive. I would like a laptop for bringing to school and traveling but if the imac is much better i may go that way.
