Google I/O is one of the most popular tech events of the year. It's where Google usually make some major announcements about new products, existing products and general information about the company itself.
Not everyone can make it to the exclusive event because it's in the US and the ticket prices are very high - they're targeted at developers alike because they're the ones who will benefit most from the four day event.
Today is Android day, where they will most likely announce a new Nexus tablet, hopefully an improvement on the Nexus 7. They will also most likely go through upcoming Android updates and what we should expect.
