seeing how wasy it was for the Apple tech dude to replace my broken superdrive in my pb, i was wondering if you could simply buy a superdrive and have it to replace a combo drive! i want a mb but would much rather save the extra 200 bucks (.17Ghz woo hoo) but i am weary of NOT getting the superdrive since it may just come in handy (although a year of owning a pb i have never used it to burn a dvd)... I somehow doubt you can since Apple doesnt offer it anywhere but didn't know if anyone had had it done.
