Well, I understand very well why Apple is determined to keep the simplicity of their mouses. I remember reading that a study conducted by Apple in the early 90s determined that 1-button mouse systems created 10% less volume and traffic on help-desk calls than 2-button mouse systems.
If you've ever worked on (PC) a help desk, you'll know how thoroughly irritating it is to try and click this, right-click that, then click the other in a Windows machine. I find I often have to say things like "Click Start, Settings, Network Connections. Now right click on the Local Area Connection icon... No you must have double clicked it. Go back. ... By clicking on the back button on the toolbar there ... OK, now right click the icon this time. OK, now scroll that middle box to 'Internet Protocol TCP/IP', and click it. No, not uncheck it. Just leave it checked and click it so it's highlighted ..."
I think Apple is EXTREMELY wise in shipping their computers with a simple, one-button interface and no ambiguities that couldn't be worked out on a telephone to a computer illiterate. That they also provide the option to plug in more complicated mice, and add third-party features later on, makes it better for users like us who actually know what we're doing. But lets not confuse the way expert users like us want our computers setup with the way apple should set them up from the factory!
