I’m not sure your assessment is right. They let iPods run on windows and made a janky version of iTunes for windows so it was operable, but I don’t think they ever treated iTunes for Windows as a priority. So, sure they knew iPod was best in class, and people bought the product for use with either platform.

But where’s the iMessage analogy? It’s not like all of Android would get better because of iMessage, they couldn’t actually sell anything based on an imesssge port, so where’s there incentive? Where’s the example of them absconding on a principle of “best product wins” when they aren’t selling a product associated with the cross platform access?
