I have a late 2008 MBP with Core2Duo 2.53gHz, 4GB, Nvidia 9400/9600, OCZ Vertex 2 60GB SSD, and I'm wondering how it would compare with the latest MBAs. On paper, it beats it out of the water. But I keep reading that the new Airs are much better than they are on paper. I use AutoCAD 11, CS5 (InDesign, Lightroom, PS), Office 11, iLife 11 and iWork 09.
