>Apple has been able to migrate between 5 processors during its existence by breaking backwards compatibility and even remove entire processing subsystems from ARM chips by removing 32 bit code compatibility.
I would consider myself an Apple evangelist, for the most part, and even I can recognize what's been lost by Apple breaking backwards compatibility every time they need to shift direction. While the philosophy is great for making sure that things are modern and maintained, there is definitely a non-insignificant amount of value that is lost, even just historically but also in general, by the paradigm of constantly moving forward without regard for maintaining compatibility with the past.
