Aluminum does not necessarily equal aluminum. People joke that Cannondale's aluminum frames are as thin-walled as soda cans. It's not really true, but they're definitely thinner than most common, cheaper aluminum frames.
But, yes, beyond that, all the little weight savings add up. In car racing, they say that it's easier to shave 1 pound from a hundred places on the car than it is to cut 100 pounds from one spot.
Same for bikes. The guys who go out of their way to build as light as possible look for a lighter stem, saddle, seatpost, fork, crankset, crankset bearings
, cassette,... shoot, even the little bolts that hold parts to the frame are fair game for weight savings.
