Clear your evening, you'll need in excess of three hours for this one!
If you missed todays mammoth keynote from Google I/O 2013, there's no need to be disheartened. You've got a couple of options. The first -- and one we recommend -- is to hit the Android Central Google I/O portal to catch up on all of the days news. Once you've done that, Google has put the whole thing online for you to watch back at your leisure.
Be warned though, you'll need to clear your evening. All of it. Or watch it in two parts. The keynote clocks in at well over 3 hours long if you count the Q&A time at the end with Larry Page. Which you should, because it's Larry Page. So, enjoy it, and drop into the comments below and let us know what your favorite part was out of everything you saw today.
