Which do I want a mac book air or mac book pro. Which will give me the most bang for the buck. I need a dvd drive once in a while and I know that the pro has one. I do want 4 gigs memory. I am told by apple that the air loads faster than the pro, I don't understand this as the pro is more money. I would appreciate thoughts on this. I use a imac now. My computer use is not specialized and I am not into to phots and the like Please let me hear some ideas on this. Thanks Don
