Ok, I am pulling my hair out trying to decide which one of these models to get. I can not decide! This laptop will be used solely for audio work, no video games at all. Is the 2.0Ghz i5 processor enough to handle Logic Pro sufficiently? I know I can get an external monitor with the 13", but just the idea of having a Quad Core 15" is making me hesitant on the 13". $600.00 is a lot of money if I will not be tapping into most of the available power the Quad Core has to offer. I would be able to put the Vertex 3 SSD drive in the 13" where as if I went the 15" route I would have to wait on the SSD. On the other hand, once the SSD drive is in the 15" I will have a monster! Will the screen res of the 2011 13" model really be that bad if I am not playing video games? The 15" does seem to be a lot more future proof however. Decisions, decisions.
