If the year is 2011, you are likely watching the above video on a Mac OS computer or a Windows computer. Those two obvious possibilities represent only the tail end of many not-so-obvious choices, the ones that determine, for better or worse, the direction that technology takes. Some things win and other things lose; some operating systems succeed, building on previous ideas, and others end up in the trash can of history. Or, in the case of Windows (which Apple once claimed "stole" the idea from Mac OS), the Recycle Bin. The trash is where Xerox's Alto operating system ended up after inspiring both Steve Jobs and Bill Gates to develop their own graphical user interface, the front-end of computers that we now take for granted.
