Although this message is comforting in my IMO the comparison is not that relevant. There is difference between digital and physical goods when it comes to marginal cost, complexity, and other limits in serving each additional customer.. Also if it is online only marketing with no "human factors" (as in the case of db/OS vendors) involved in the sales process then again the make or break avenues are limited.. Good things are with digital goods you can iterate quickly both in terms of product features and getting the message out.. so if you let nature take its course then a strong and smart competitor will kill you..If you have to win then you have to outsmart at least in a niche..
