Obviously, any pithy observation is by necessity overly simplified :) However, there's a lot more truth to it than otherwise. E.g, your first point, the painful status quo. My previous company addressed the job search market, in which most people are very unhappy with the status quo solutions; and our particular solution, I feel, was about 40-70% better than existing ones (and also a new paradigm), nonetheless, people weren't really readily jumping ship. With search engines (including a vertical one, like ours) evaluating comparative quality is actually pretty hard, which washes away a bit the easy switching cost (I don't mean expert comparisons; I mean average user looking at average queries).
