If you missed Google's live event where they presented the new Nexus 7, Android 4.3, and the awesome Chromecast, can now watch the whole thing all over again in the video below.
Personally I was most impressed by the awesome Chromecast HDMI adapter, with that you can make an incredibly cool, and useful SmartTV out of any TV, it only needs to have a HDMI port. Nothing else. And the price of $32 is very cheap too.
I just wish I could buy it here in Sweden :(
