I'm currently on the market for a MBP that is powerful enough for the work that I do. My Mac Pro is my main workstation but I will be traveling more often now and need something on the road that is backpack-able and also just as powerful or CLOSE to my main workstation. Now I know it would be hard press to find something on the market right now that is exactly like my Mac Pro, but I am open to suggestions and looking to get the closest laptop version of my main workstation. The processor in my Mac Pro is a 3.2GHz Quad-Core Intel Xeon Nehalem. What's the closest MBP to that?
