For the now, the M stands for Developer. But that won't stop the rest of us from running the Android M preview.
Just like last year, Google dropped a developer beta preview of the next version of Android into our laps. Android M is still in the oven, but enough work is done on the new APIs to give them to the developers who need them. That's cool — and important. Devs need time to get ready for new features and changes to existing ones.
But because this is a public beta, people who aren't developers are free to download and install the Android M preview on their Nexus 5, Nexus 6 or Nexus 9. Or even the Nexus Player. We are doing it. I imagine more than a few of you guys are doing it, too. You know what happens when we have a question — answer the poll. Maybe we'll form some sort of club!
