I assume it phones home to Google?

Yep.

In order to develop for the platform, you need to register your application[0], and your device[1]. Also you cannot even run your own application without getting google's approval[2], which costs $5..

Then, at runtime, the device will first validate that the app you are trying to run was validated, sending the `AppID` to google.

Wow, that's draconian. Are there any devices a bit more open that are in the same price range and support the same feature set?

so far I am very happy with the raspberry pi as a homebrew platform ..

PROS:

- ports: 1x wired net, 4x usb 2.0

- runs linux, super easy to extend/modify (access via ssh from other devices)

- super reliable, with uptimes of months

CONS:

- bigger in size, and not beautiful without a case (except if you like electronic pr0n)

- requires an HDMI cable

- requires an external power source

Can the raspberry pi run off a TV's USB port similar to the Chromecast?

I have had issues running a wifi dongle when connecting using the tv's usb port - admittedly this is with the old version and not the new one with the updated power circuitry.

However, I have had no issues using usb power from the tv with a LAN connection - this is using Kodi which I suspect will increase the power pull. YMMV

YMMV, It looks it can. https://www.raspberrypi.org/forums/viewtopic.php?f=91&t=9322
