jbrodkin writes "Two decades after Linus Torvalds developed his famous operating system kernel, the battle between Linux and Microsoft is over and Linux has won, says Linux Foundation Executive Director Jim Zemlin. With the one glaring exception of the desktop computer, Linux has outpaced Microsoft in nearly every market, including server-side computing and mobile, Zemlin claims. 'I think we just don't care that much [about Microsoft] anymore,' Zemlin said. 'They used to be our big rival, but now it's kind of like kicking a puppy.' From Android and the Amazon Kindle to embedded devices, consumer electronics and the world's largest websites and supercomputers, 'Linux has come to dominate almost every category of computing, with the exception of the desktop,' Zemlin argues as Linux approaches its 20th anniversary."
