Ask yourself if your business and interest would exist if the smartphones didn't exist. Then assume that it doesn't exist tomorrow because someone decided that a license is changed, decided that they didn't want to approve your app or decide to stamp on your turf. Your world will collapse.
Part of business is planning and resilience. It's something most Apple developers have not realised yet which is why so many of them are going to get canned by Apple over the next few years. This is purely down to being unrealistic, inexperienced and cash hungry.
The whole smartphone/cloud platform thing going on at the moment is a seriously harmful process both for business (in the long term) and computing as a whole. It seems to be based wholly on vendor profiteering and quick wins rather than genuine progress.
