While i do not profess to be computer geek, i did make my living for years on computer systems. I spent most of my time in the Unix and VMS world but had my fair share of time with Windows which I do not consider a true operating system.

I see alot of Macs in movies yet Macs arent as widely used as Windows machines. Of all the people I know who are Mac users only one fully utilizes its potential. The rest are lucky that OSX is built on Linux.
Actually Mac OSX is a fully licensed version of UNIX. While Linux is Unix like it is not the same. Actually like Linux, Unix has so many different versions that the Berkeley Egomanics that created it would not recognize many of them.

Because of the holes in Windows most of the far east, Japan leading the way is moving almost entirely to their version of Linux.
