My fiance has last year's 15" MBP base model, and I just bought the 2011 13" MBP. I'm using it for music production and DJ'ing, she uses her's for school and basic browsing. Here's what I'm wondering... How do the two models compare processor wise? She knows I use mine only for DJ'ing, and was asking if the bigger screen would benefit me. My worry is if the processor would find any bit of drag? I DJ using Traktor, and I know it doesn't pull a ton of processor, but if I'm using any good number of FX, I know it drives the pull up higher. Also, how does moving Apple Care around work? She has Apple Care on hers, but I haven't purchased it on mine yet. Can I buy it with her information and have hers transferred to me? I'm not terribly familiar with Macs, and I'm pretty sure she's using the previous OS. How would I go about clearing her HD and updating to Lion so I have a clear system to work with? I think that's about it! Thanks for the help!!!
