Hi Everyone. I currently have a mid 2010 MBP 13", 256 Crucial M4 SSD, 8GB Ram, 320M Graphics. I wanted to upgrade for some time now but still not sure if it's the perfect time. I am an application developer. I am worried that the 15" might be a little big for my taste while I am on the train. I do sometimes play some SC2 that my current laptop only runs at min settings. I run IntellJ, Jetty, Tomcat, Xcode, and VM's that enjoy eating up my memory. Option A) rMBP 13" 2.6Ghz, 8GB ram, 256 SSD. I want to get the 2.6Ghz b/c it will added 100Mhz to the Intel Iris 5100. Cost: 1,599.00 I am worried that this laptop might not be a huge update from my 320M. Option B) rMBP 15" (Early 2013) , 8GB ram, 256 SSD, GeForce GT 650M, Refurbished. Cost: 1,659.00 I am worried this laptop might be a little big. It also seems like a steal considering the new $2K laptops don't come with a detected graphics card anymore. Option C) Wait or anything else you guys have in mind. Thanks so much!!
