Google doesn't make third party developers second class citizens: it makes apps using the same tools and apis as available to everyone, and distributes them the same way that everyone else distributes their apps.
This is a step forward for Apple, but for example: Safari will remain the only browser available on iOS, and Apple's version of Safari will remain versions ahead of UIWebView meaning that any non-Safari browser will remain inferior by intentional design. True competition is prevented by design, and it takes 5 years to open up something as basic as the keyboard. How many more years until browser is opened up? 5 more?
It's an interesting move as far as platforms go, but I know that it's no where near what I want from a platform. It's still locked down, under featured and heavily controlled. For a non-tech user or someone who wants a dead simple phone, it seems great. But for those of us who love our devices, love customizing them in and out, and love trying to create the best experiences, Apple still is not a choice: we can't compete with Apple apps, we can't use their in-house APIs, and they still offer us inferior versions of the software/APIs that they use inhouse.
