Today in San Francisco's Moscone Center Google introduced their new Nexus 7 tablet to a cheering throng of developers (but of course you know that already!). Above you'll find the video of the Nexus 7 part of the company's presentation which shows the tablet being put through its paces with the new Android 4.1 Jellybean OS, as well as shows some of the Google media, content and services that are part of the tablet's ecosystem. Enjoy!
