It's not about user-facing features. It's about the damn API version! Fragmentation is a problem for users AND developers. With the news about the Galaxy Nexus, Google is basically telling developers to keep targeting old version of Android and avoid the latest APIs. As far as I'm concerned, the Android Support Library is the one true API.

Android API version isn't as big of a deal anymore, since they've been moving to offload everything onto apps which are updatable separate of the OS.
