I own several, and they're by far not junk but you're entitled to your opinion and I respect that. The one thing you can't deny is that the Roku is one device that actually gives Apple some competition.
It's not Google's fault that Samsung put Android on such a crappy device. If there's a activation on their servers they're going to count out. Blame Samsung and whoever decided to buy a phone with running a 3 yr old OS.
