Time has come to replace our downstairs laptop (2010 MBP). That machine will go to work to replace a 2007 black Macbook, which is on it's last leg. At first, going 13" seemed like a no brainer, we've seen older 15" models and they seemed too big. However once while walking in a Best Buy recently, the newer models didn't seem to have as big of a footprint. These new updates make the decision of 13" vs 15" MBPr more difficult. 13" has newer processor, 15" does not, but it is a quad core i7. Processor means little to us. At most light video editing of iPhone footage may happen on occasion. 13" now has 8gb of faster ram, but 15" comes with 16gb. We have 8gb in our 2010 and it seems enough, though my wife leaves every app/tab open and we use fast user switching. 13" has better battery life, but that means little since it's primarily a home machine. 256gb should be enough storage. Most media is stored on a drobo, hooked up to an iMac. So comparing the $1500 13" MBPr vs the $2000 15", the main differences are the processors, screen size (I would like more), faster RAM,and the intel iris 6100 vs iris pro graphics. I'm not a gamer, but I would enjoy picking up SimCity again or the new Skylines game. Thoughts on the new 13" vs now older 15" MBPr would be appreciated. Thanks!
