I, like the original poster, do photo work with multiple displays on the desktop. I use a 17" Powerbook, I find the couple of inches wider is very comfortable, is still easy to transport and gives me lots of desktop real estate. I also will hook a second dsiplay in once in a while to get the needed real estate once in a while. I just sold my 12"....the display was just too small for anything other than writing and browsing. I miss it already, as my macs are parts of my body
