Android: Over 500.000 activations per day!

Andy Rubin just twittered that over 500.000 Andorid-powered devices are activated per day! Remember when Mister Rubin announced that 300.000 were activated each day? Yeah, that is only seven months ago.
That means: 60% increase from December till now... really stunning, isn't it? It is also a fact that Android is now the undisputed #1...
