I wonder about the privacy issues here to be honest. The "FAQ" linked to by the site says "we can go to ign.com on it" but what happens if we do? Does Steam see that we went there? Do they log that? If we log into our bank accounts on the device does Steam see that too? What telemetry are they collecting? Does changing the OS prevent all of it? Will there be ads?
It's cool tech, but I have to ask how will it be used against me? Will it only be pushing me to spend more of my money on Steam games or is there something more?
