When I go on vacation, I'm damn glad for the wheels on our suitcases. My wife likes to push the limits of the 50 lb limit for checked bags, and while I guess it makes me less of a man in your eyes, I have no shame when it comes to rolling that bitch around instead of carrying it.
Now, when someone has a laptop bag or briefcase that rolls (basically something under 20 lbs), that is infuriating.
