I just replaced my 2008 MBPro with the Retina MBPro, and all I can say is that if you use it for actual work, you need to upgrade ASAP. The difference in performance is HUGE..

If your old MacBook didn't have an SSD, that is probably what most of the difference is.

Or do you mean that the retina screen makes you perform better? :)
