Google Chromecast First Impressions and Photos
The easiest way to watch online video on your TV? Not even close
First, it's not a standalone device. To use the Chromecast—to even set up the Chromecast—you need another compatible digital device.
Second, as alluded to above, Chromecast is extremely limited. You can stream content from the Google Play Store, Netflix, and YouTube only.
Third, those pictures where you see this USB-dongle-looking-thing sticking out of the side of an HDTV, creating a clean look? Completely fake. The Chromecast requires a USB-based power cord and, on most TVs, an HDMI extension cable.
