I dont see the reason for a blu ray drive in a MBP anyway?
if your gonna use it on your TV get a blu-ray player its cheaper..
or get a PS3 you get games and a blu-ray player.
you cant get 1080p in anything but a 17" MBP so the vast majority...
why not just download from itunes? its cheaper than a blu-ray and more easily useable on other media like TV just you flash memory sticks?
