What developers can expect at Google I/O 2012

Since when does a vendor-sponsored developer conference sell out 5,500 seats in just 20 minutes? That’s what happened when tickets for Google I/O 2012 went on sale this week. It beat last year’s record of an hour, which had also raised eyebrows.

One easy answer is that Google I/O sells out because of the swag. Tickets aren’t cheap, but each attendee gets a gift bag with a street value that typically exceeds the price of entry. Last year’s goodies included a Samsung Galaxy Tab 10.1 tablet and a Chromebook. Previous years’ attendees received Android smartphones.
