Well my trusty 1st generation Macbook Pro finally gave up the ghost. So now that upgrade I was going to make "someday" is going to happen in the next few days. I found a good price on the late 2011 2.8 i7 13" with 4g ram, but the 2012 2.9 i7 13" with 8g ram AND usb 3.0 is only a few hundred dollars more. So I'm wondering if the difference is worth it. -Will I notice that much of a speed increase? -How much better is usb3.0 really? As a professional photographer I do transfer a lots of large files (up to 16g at any given time) so transfer speed is very important to me. Plus my card reader is actually usb3. I've read all the benchmarks, but am interested in real world experience with the 2012. Sadly the retina model is not an option at this time. I might consider an ssd upgrade down the line though. Any thoughts on the 2012 performance?
