So 900 million Android devices back in July[1] and even if 5 million devices had Android that is a total of 0.55% of all Android users. Still worth it?
>> "Several million people who use Android had downloaded Google Reader."
That says nothing about usage though. I downloaded a lot of Google apps when I first got an Android device. Most of them I opened once and never again. I think this experience is common with apps.
