Exactly, thats the difference between Andrew Tanenbaum and his "theories"
EXCUSE ME but before you go on touting stuff like that don't forget that before the Linux kernel there was Minix and there IS something called Amoeba and there are books on OS and networks whose eloquence is UNPARALLED.
So before you start FUD about AST who IS one of the golden greats of computer science PLEASE get your facts right.
and Linus who built a practical kernel - which works!
don't forget Minix... Linus certainly didn't while writing Linux.
People,
especially businesses give a damn about freedoms and such.
they do if what they use would destroy their business later.
They use
whatever works and is _cheaper_ :)
again if its cheap in the short run but kills the business in the long. It will never last.
