Execution matters. Zune Pass died a few months ago. I can still use account credit I put on my AppleID from 10 years ago (in fact I still have a few bucks on one of my early accounts).

A small startup that gets squished by larger competition has an excuse as to why it shut down services and let down it's customers. Microsoft has no such excuse. They failed to compete, then the failed their customers. Innovation is wasted if it's improperly handled.
