This is actually a pretty weird continuum now between the three set-top boxes. The Apple TV is really focused on getting content onto your TV. Out of the box, you can stream content from Amazon, Youtube, Hulu, Netflix, etc. without an additional iOS device. With Airplay, you can stream content from your OSX/iOS devices to the Apple TV. Roku does the streaming half of that equation. It'll stream basically any online service to your TV. On the other hand, the Q seems to handle the half that the Roku doesn't. It seems entirely focused on streaming personal content to your TV and speakers.
