[TUHS] System Economics (was is Linux "officially branded UNIX")

One of the problems was the hardware system price ratio to software system price. When you could get 
a 486 PC for $5-10k and the SysV source license (for 4.3BSD!) was $100k, it seemed rather monstrously 
disproportionate. :)

This mismatch didn't exist in the Minicomputer world, where a VAX cost rather more than $5-10k and 
the price for a source license was thus not disproportionate.
