Preston Gralla of ComputerWorld (and a few others) has been blogging the eventual demise of Linux when Windows 7 hits the scene and takes over the hot netbook market:
You can be sure when Microsoft blitzes the world with a massive advertising campaign for Windows 7, they'll be spending many millions promoting Windows 7 on netbooks. And given that marketing muscle, Linux most likely won't stand a chance, regardless of which operating system is superior. (More reasons Windows 7 will kill Linux)
Windows 7 features a much slicker interface than Windows XP, is easier to use, and Microsoft will spend many millions of dollars to push its use on netbooks. So when it's released, expect Linux use on netbooks to drop. (One more reason Linux must fear Windows 7)
Of course, none of this rambling seems very much to the point. As one commenter pointed out, Linux will continue to be Linux no matter how much money Microsoft spends or what Windows 7 does. Linux isn't going away unless the entire Linux community decides to disperse and stop developing and growing. It's not dependent on profit marginsâ€¦or even marketing.
