Linux only has a small percentage of the computing market, however Microsoft already considers it a major competition as the open source OS steals the hearts of many users. Following the hard numbers though, Microsoft also increases its market share on both server and desktop space with time. The only logical explanation is that Linux steals quite a market share from the traditional UNIX providers (SCO, Sun, SGI, HP, IBM). But only Sun seems to truly be in a real Linux trouble, as it is the one with a resistance to Linux integration to its full product range.
Microsoft now has a license to stick the Windows program on top of a REAL operating system. Some may say this would be a good thing, but I have yet to see anything that Microsoft hasn't bought, copied or stolen (Somewhere close to 99.999% of their products?) that has not suffered degradation due to Microsoft influence. I think Solaris will survive longer than some predict for one simple reason, SCO. I shredded my SCO media pack and licenses two days ago, my equivalent Solaris items are as intact as my Linux distros.
