The last time we reported on Android phone activations was back in June, when daily activations were about 160,000. That means that in less than 4 months, the number of Android phone activations has almost doubled, but the story doesn't end there.
Back in late October, it was announced that the Android Market reached the 100,000 app milestone. While those numbers have likely climbed much since then, Google has not updated the statement, as shown in their product page for the Nexus S.
It is also important to remember that these figures only represent devices which are phones, and as such, can likely access the Android Market. Many companies are producing Android tablets without 3G or cellular connection and Android Market access, and therefore are not being counted in Mr. Rubin's calculations.
If these kinds of figures are not enough to convince the skeptics that Android as a mobile OS is still growing, and has a bright future ahead of it in the smartphone and tablet segment, then I'm not sure what is.
