They said that 10 years ago, but it hasn't made any noticable impact yet.

Less and less you mean? Dell have actually just stopped shipping machines with Ubuntu as nobody is ordering them anymore. According to my own stats, the percentage of people visiting my websites who are running linux is falling - not rising. Perhaps you live in a country where it's more popular - but it seems to be dying here in the UK.
> Except that, outside the PC Desktop and XBox, Microsoft has at most 20-25% of the market.
Not sure where you get that from! They have a 65% share of the server market for a start. src. Your figures might be correct for *web servers* perhaps, but certainly not for the server market as a whole.
> Except that C# is a ticking time bomb that will either go free
Huh?! Unlike Java, C# is a totally open and free language - it's a public standard just like C and C++.
