Not yet legal
In most of the United States, 21 is the legal drinking age (though you can join the military long before that -- interesting). In most of Canada, it's 19. Right in between this year, at age 20, is the IBM PC, or more accurately, 2001 is the twentieth anniversary of the introduction of the IBM 5150, progenitor of almost every popular personal computer today except those made by Apple.
So, if you're like me, and right now you're sitting in front of a computer monitor, with a keyboard in front of you and a computer CPU housing on the floor or desk nearby, you have IBM to thank. (Or to blame.) The mouse is Apple's doing, however.
