Google's Andy Rubin tonight on Google+ announced that more than 700,000 Android devices are being activated every day. That's 29,166 devices (more or less) activated every hour. Or 486 devices every minute, or by the time you finish reading this post.
Rubin also explained what counts as an "activation," saying:
"We count each device only once (ie, we don't count re-sold devices), and "activations" means you go into a store, buy a device, put it on the network by subscribing to a wireless service."
That's up just a skosh from the 500,000 devices Rubin announced in June. Dang.
