I bought a macbook air a few months ago as my first mac. I'm now loving the whole mac thing. However, I wanted a more capable system, so I just ordered a new 2.53Ghz Unibody MBP. My question is, what is the best way and/or the easiest way to transfer all of my files from my macbook air to the new system? I don't currently have an external harddrive, but I have no problem buying one if it will help. If you think I should own an external harddrive, any advice on which one? Also, is there a guide anywhere for how to do this. I'm afraid of losing my itunes (I only have an iphone 3G, not an ipod). Is there a way to just connect the MBP to the MBA and transfer? Thanks for any help!
