Unfortunately, neither finished software nor durable hardware are compatible with the imperative for growth that firms operate under in a capitalist system with unlimited marketing. Once the market is saturated, next year's revenue must come from a product that is different from what the consumer already owns. It must either actually be better, or marketed in such a way as to be perceived to be better. Usually, the marketing option is easier and more reliably reproduced year after year.
