In the early days of Mac versus Windows flame wars, the debates about secondary mouse buttons often quickly degenerated into something that looked like the end of the Dr. Seuss classic The Sneetches. Both sides would split hairs over what became an arbitrary issue of personal preference. (This was in stark contrast to the debates over the use of function keys. Now that was a war worth fighting!) Once Apple adopted USB, Mac users gained access to a number of very good multibutton mice from Logitech, Microsoft and others and the argument seemed moot. Mac users who saw the benefit of such mice could get them, and those who didn't need the extra functionality soldiered on with one finger.
Still, for many years even after the arrival of Mac OS X, which supported multibutton mice out of the box, Apple held its ground with the one-button mouse. It did this even though it had supported right-click-friendly features such as contextual menus since at least the days of System 8. Now, as Apple has brought out its (corded) first multibutton mouse, it's treated its reversal with atypical facetious self-depreciation on its Web site: "Alas the fate of the one-button mouse in today's multibutton world. Who has time for intuitive, elegant design when there is so much clicking to do?" Behold Mighty Mouse, the namesake of the animated resilient rodent celebrating his 50th anniversary this year. Apple is using the name under license from Viacom, otherwise known as Mighty Media.
