I went on a field trip to the local computer store and (cringed) headed to the PC laptop isle. There I examined every mouse button and clicked every clicker, left and right side. They were flawless. I was envious. Even the worst clicker on the cheapest laptop clicked better, quieter and was more firm than on my G4 PB 15in. Over to the Apple section, I clicked away on the 17in, 12in and the 12in G4 iBook and found they performed pretty well, left and right. However, on the 15in PB's and the 14in iBook, the clickers clicked horribly, especially on the left side, just like the ones in my lab, like a piece of crap. The Apple Specialist, in the store within a store, said that the mouse button was normal, seemed OK to him...or I can use the trackpad and walked away. That's OK, what's he going to do anyway? Well, now we know.
