You're thinking like a computer nerd; Linux's big move has been to quietly take over millions upon millions of TV screens, all while no one in the tech world would label such consumer product displays as "desktops."
TiVo is a Linux box. TiVo watchers don't care IN THE LEAST about regulatory requirements or vendor support. What they care about is that massive high-definition big screen plasma TV display that commands their den's center wall...and they want their digital movie/show/game content displayed on that wall at their command.
So as the computer and TV converge, Linux suddenly and unexpectedly finds itself controlling the most important video screens in millions upon millions of American households.
Already these Linux boxes are connecting with existing home networks. Already these Linux boxes are on the Internet (TiVo downloads software and content updates nightly via phone, DSL, and cable modems).
So step away from your ancient computer for a moment; your computer isn't running a giant plasma high-def TV in your den.
But there is a computer that is running millions of them...wrapped up inside a Linux box and packaged as TiVo.
This is the new revolution. This is *precisely* what Bill Gates predicted...the convergence of TV, computer, and telephone...yet it isn't happening on any of Gates' operating systems.
