I've got an older Macbook pro that I souped up with some aftermarket memory and a solid state drive from OWC. The specs are: 2.26 Intel Core 2Duo, and 6 gigs of ram. I'm a photographer, and primarily edit off a pretty speedy mac Pro. I would LOVE to have a mobile setup that can keep up (currently it's fast enough to use in a pinch when I'm on the road, but for any heavy lifting I have to get in front of the Mac Pro). So when the new Macbook Pros came out, I figured they were worth considering. The thing is, I wonder if one of the new ones will really be that much faster. I've already got the SSD. It's just a couple gigs of ram less than I would get with the MBPro. It would seem to me the main differentiator would be the processor. If that's true, are the new processors (I'm mostly looking at the 2.5 and 2.9 dual cores that come in the 13") going to be a noticeable difference? For what it's worth, the main programs that I want to have a lot of power for are Lightroom and Photoshop. Also, while I hear the retina displays are amazing, it's not a selling point for me right now.
