Apple Shipping 2 Button Mice?

Joshua Marshall writes "I saw today as I was idly browsing some Mac web sites, a Q&A mentioning that Apple will be shipping two-button mice as an option with its new Yosemete G4 machine! (shipping early next year.) One more reason to buy a Mac and LinuxPPC! If you want to read it, you'd better hurry, they update the site once a day. (It's at the bottom of the page) " I'm amazed. How can this be? 2 buttons seems so... confusing. 3 seems positively counterproductive *grin*.
