Google has just kicked off its I/O keynote with some big new numbers to share. It now says there are 400 million activated Android devices out there, and one million activations per day. That's up from the 100 million activated devices it announced at Google I/O last year, and 200 million it announced last fall, while the activations per day are up from the 900k it confirmed just earlier this month. As Google was quick to point out, that translates to about 12 devices activated every second, and it's happy to note that things are "definitely not slowing down."
