Linux will become a lot more viable on the desktop when the price of hardware falls to a level that makes the windows license a very significant percentage of the overall cost. In 2002 it costs me 800 bucks for the hardware to build my own system. Now you can pay like 300 for all the parts you need to build a system. Lets say it cost a about 100 bucks to go out and buy a windows license. In 2002 Windows would have been about 11% of my total cost (100 bucks for windows + 800 for hardware is 900 total). Now the total would be 25% if you buy a 100 windows license for 300 hardware. I don't know how much it cost a company like Dell or HP for a windows license (I'm sure it under $100, but I'm guessing it is more than $50, anyone know?) but it is becoming a bigger percentage of the cost of a PC every passing day.
