Linux did not win, yet
http://www.cio.com/article/3141918/linux/linux-has-won-microsoft-joins-the-linux-foundation.html Yes, Linux won on servers. Unfortunately... servers are not that important, and Linux still did not win on desktops (and is not much closer now than it was in 1998, AFAICT). We kind-of won on phones, but are not getting any benefits from that. Android is incompatible with X applications. Kernels on phones are so patched that updating kernel on phone is impossible... 
:-(. This means that Microsoft sponsors Linux Foundation. Well, nice, but not a big deal. Has Microsoft promised not to use their patents against Linux? Does their kernel actually contain vfat code? Can I even get source for "their" Linux kernel? [Searching for Linux on microsoft.com does not reveal anything interesting; might be switching to english would help...]
