I'm looking at replacing my 2007 MBP with a newer model as a stop gap to hold me over until the Retinas have more storage for the price and are perhaps a little more affordable. I'm considering one of the above-mentioned models, but thought I would put this out there to get some additional advice. The difference in price between these two 15" MBPs is only $300 ($1229 vs $1529), but I'm wondering if it is worth it. The money I save may go towards a Thunderbolt Display, and or an SSD/HDD setup. I currently am using a 750GB 7200 rpm HDD and will likely swap out the stock drive for either that or a dual drive setup. My biggest performance concerns are running Logic Pro and using the external TB monitor. USB 3 isn't a big deal for me. Thank you for your thoughts.
