Isn't this how open platforms are supposed to work?
Surely rapid iteration and deployment is a good thing, and the resulting compatibility chaos is a natural side effect of a vibrant and active market developing around the platform?
Early adopters are used to half-baked ideas and fast obsolescence, and Android is definitely an early-adopter's platform still.
It's one of the more annoying aspects of open source, but eventually things settle down and the technology moves into the mainstream. Hopefully it can achieve some stability by then as mainstream consumers won't put up with it.
