Actually, the adoption of linux is the seque into a new generation of property rights. MS has been something of a medieval "robber baron" with a castle on the river, demanding tribute from every boat that passed.

Your article stated clearly that the money doesn't come from the OS, but rather in CLIENT SPECIFIC APPS that can be custom designed for each enterprise. If I hired some codehead to write apps for my business, it would cost me a fortune. However, if OS were to command 30-40-60 per cent of the market, there would be tons of guys out there ready to write and tinker with end user apps for small to mid-range businesses...... OR to write custom end user apps for "off the shelf" software. Try getting QuickBooks edited now to fit the needs of your office!!

Nothing new about socialism, this is just a new package.
