When doing all that "PRO" photo and video work, you shouldn't be doing it on a 15 inch laptop anyways, regardless of whether it's matte or glossy. I know my colleagues have connected their mbps to a matte 30-inch LG or NEC S-IPS display and worked from there... Matte or glossy, you're not going to get the color accuracy that you listed with a TN panel.
Yeah, you might argue that you sometimes might need to work on the fly, but then even if you DID have a matte 15- or 17-inch mbp, you'll end up with half the job that can be accomplished on a 24+ inch S-IPS monitor.
Just like my thoughts!
