Can you stream stuff from your Roku into a tablet? If so, that'd be awesome. What about a Chromebook? It sounds like a Slingbox and SlingTV might be different products, are they?
Oh yeah, like Grey, we've got a Roku3. One of the upgrades is a head phone jack in the remote. When I was researching, that was a feature I did not care at all about, but it's great to be able to watch a show on my big TV in the middle of the night without bugging my family.
