I recently bought a top of the line MBP 17 inch, and they mostly offered the glossy monitor. I paid extra for the matte screen, but the problem with that is that your eyes must be exactly in line with the monitor, or else the visual representation changes drastically. Up to what I'd estimate to be about a stop lighter, if you're not directly in line with the monitor.
But I found that glossy option to be completely objectionable; I don't want to see myself, when I'm tethering a job in direct sunlight. Very irritating.
I don't know of a good option. Maybe paint the sheetrock behind your editing station very dark grey, and wear your fashion-black tshirt when you're retouching, and hope your hair is combed, because if it's not, it's gonna bug you to death while you're working, when you see your reflection.
I retouch with the older matte Apple 30" monitors, calibrated with EyeOne Photo, and I love those monitors. Maybe not as accurate as a pricey Eizo, but still, a very nice monitor, when calibrated.
