Roger Mercer, you've had the smartest response out of everyone here. Compatibility is stronger than quality, because everyone has a different taste of how they like their software served.It doesn't feel safe to have Apple single handedly running everything. There have to be many hands in the cookie jar (Third parties) doing the same applications in different styles or only a minority will feel safe. That's why PC and Microsoft have the majority of the market. The user feels comfortable with the highest amount of compatibility (safety).
