FWIW, considering what's in it, Chromecast with Google TV probably has positive margin in the USA. It is using only off-the-shelf very cheap components. Except for USB-C part, you can find same-speced boxes for 30$ on chinese market. I'm not even going to mention the price of Chromecast with Google TV in Europe, for which Google probably has 30-50% margin, (It's 70€, so 70$ tax-excluded).

This doesn't hinder your argument though.
