The things that appeal to me about the matte screen over the glossy.
I'm a programmer, I sometimes work with bright lights behind me, although most of the time I code in the dark, and the reflections *could* bother me.
The extra pixels will make it easier to see more tracks when I'm producing music in my spare time. Although this is just a hobby for me, it's still important I consider it when buying a laptop.
Like you, I code and spend an ungodly amount of spare time in Logic 9. I'm upgrading my 2006 MBP (matte) next week.
Taking a quick cursory glance at glossy in the Apple store etc, yes, glossy looks pretty snazzy. But if I was in terminal/cli or using a DAW, glossy would drive batsh*t in 30 seconds flat.
