I wouldn't regard the Apple mouse as just having one button - after all, click on the left side of the scrollwheel and a left click is detected, click on the right side of the scrollwheel and a right-click is detected.
The main downsides to the Apple mouse is the very short USB cable, low scanning resolution (no good for games) and they dont last long, even though they dont look for feel cheap.
