I currently have a 2.26 GHz Intel Core 2 Duo with 4GB ram 13" MBP (NVIDIA GeForce 9400M) I do light photoshop work (no client stuff, just personal blogging so minimal edits) and a bit of lightroom work. If I could open files, do a little light editing without any drag, I'd be happy. My MBP now is perfect, but I'm really drawn to the lightness of this new air. The reason for getting the 13" MBP was because it was the smallest MBP, but the fact that it could be smaller is even more appealing. My sale on this laptop will buy the new air and even though I'm getting less power and performance, the smallness of the air is what I'm going for. My only concern is how much less performance I'll be getting? I don't know much about tech specs, but any advice would be appreciated. Am I crazy for "trading" this in for the new air?
