Awesome, finally a hard magnitude!
Imagined statement from Google boss to employee: "So remember, when you break something like HDCP, you're affecting millions of units."
What will be interesting to see is how the sales are outside the US where many of the folks who bought one probably were from outside the US! LOL
It's a good thing cause when you breach the Million unit mark there is enough there to encourage content providers to support it.
You know my feelings here, I'm more interested in getting content providers to support flinging content to other monitors and I don't care what device is used for that.
Once it's in the App and Website adding different methods (mDNS, AirPlay, DLNA) is easy....
But getting them to put that Icon to select the device is the hard thing to get them to do.
Chromecast selling the way it has will help and Roku's new dongle will add to that.
