This is the classic apple approach - wait to understand what the thing is capable of doing (aka let others make sunk investments), envision a solution that is way better than the competition and then architect a path to building a leapfrog product that builds a large lead.
Apple waited on smartphones? I thought the original iPhone was basically first. Do you count blackberry and palm pilot as Apple waiting to see?
The difference, if any, was focus. The premium on smartphones before Apple hit the market was on business/professional users who could afford the high premium. Apple instead targeted making a premium consumer product - that professionals then started to jump to over time, depending on how addicted they were to their blackberry keyboard.
