I wish Google would take the problems of cross phone compatibility more seriously. Without it the entire purpose of Android is compromised, and yet, they don't seem to put much effort into ensuring compatibility or motivating manufacturers to ensure it.

For example, while I support Google's decision to keep the Android market open, I don't see why apps that simply crash upon launch should be allowed allowed to be sold and downloaded to people's phones. Google can easily detect / track this kind of thing and automatically flag phones not supported as incompatible, refund users and notify the developers. On the developers side, they should have access to an extensive database of compatibility information so that manufacturers are shamed into seeing devices that are hard to support getting black banned in the market and crossed off support lists by developers.

I don't think you need an authoritarian approach like Apple's to make things better, but you need to do more than Google is right now.
