Some people like paying $$$ to people who give them valuable goods and services. Just because the distribution cost is close to zero, it doesn't mean that the value of the product is close to zero.
Thanks for the condescension. I couldn't agree more on cost not equating value - I am an avid Ubuntu user and would gladly pay for its value as an operating system. The above was a joke - apparently not a good one, but a joke none the less. It was intended to be delivered at the expense of BestBuy, not Canonical - surely you are not presenting them as providing valuable service ;) But alas, a joke that requires an explanation was clearly not a well executed joke to begin with - I retract. Thanks for the education on value and economics. sheesh.
