By last August there were 200,000 Android activations per day. In December, they exceeded 300,000 devices per day. Over 400,000 Android devices are now being activated every single day. Android Market has over 200,000 apps, half the App Store’s 400,000 count.

There are 4,5 billion application installs from Android Market to date. Android today has more than 310 devices carried in more than 120 countries.
