Om gives credit where credit's due:
And then my sysadmin, sent me an IM reminding me of The Humane Interface by Jef Raskin,
who worked with Jobs eons ago. In one of the chapter of his book, he
writes about how an Apple multiple button mouse would work. Here is an
excerpt which describes the “multi button mouse”
It seems that Raskin pretty much presages the just-released Mighty Mouse. Om's also points to the Walt Mossberg article in yesterday's WSJ where he says that models of the Window mouse do the multiple click option thing much better plus the newest version, besides being wireless, has a magnifying feature which he thinks work pretty good.
