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.

I agree completely, but the real problem in this respect is windows, not linux replacing unix. Windows already runs ninety-something % of OS-powered devices!!!! It thoroughly dominates the desktop, has a huge and growing market on the server, and is creeping into everything from Palmspilots to cell phones to BMW dash-boards! It even wants to be in your toilet! Compared to windows, Linux is just a drop in the ocean.
If, like me, you like to see more operating systems and architectures, support linux. Why? Because Linux is open, is available to IBM, Microsoft, Sun, Hp, or whoever cares, and is not tied to any particular monopoly or corporate agenda.
Should linux replace Unixes? I would hope so! It would be a great way for Unix outfits to pull their resources together, instead of fighting each other in ways that only benefit abusive monopolies like MS.
Also, linux has a pretty good chance on the desktop, so every company supporting linux might eventually help create a more open desktop environment.
