Yeah I know saying that in hindsight it's just going to go to the ONN sticks instead and stay within Google TV - but it solves the problem Amazon wanted which is to quickly and smartly move the problem away from themselves and onto someone else's loss leader.
(And Walmart already has started doing regionlocking to try to crack down on that, too! Taking an ONN box out of the US will error out in setup and complain it's only for sale in US/PR.)
