Chromecast is one of the slicker devices to come out of Google HQ in a while. After you're all set up, just tap a button on YouTube or Netflix, and BAM, whatever you were watching is now on your television. It's really awesome.
For the researchy-types like me, the Chromecast comes with two piece of software to dig through. The first is the physical device software, which, while it is sort-of Android based, it's only Android-based at the low level.
