The popularity of Android is astonishing enough that Google’s developer event ticket went live for sale around 12 and sold out in 59 minutes. The event that brought FroYo to us last year is coming up on May 10-2011 at Moscone West in San Francisco. We will not be at the show, and a lot of you might not since it’s already sold out, we will still do our best to bring the latest big news from the event and keep you updated the whole way.
The original details, while the tickets were still available was that: General registration is $450 through April 16, $550 thereafter, and $150 if you're in academia. Register now at Google.com/io.
