This device is my go to method for all streaming needs! I own multiple devices that provide streaming access to Netflix but none that provides access to amazon prime. The user interface is easier and more direct than either the smart tv and blu ray player. I enjoy shows on the Revision 3 channel such as CNet reviews, HD Nation, and Tekzilla.  The PBS channel provides access to current shows not available on Cox OnDemand.  Would love to watch Fox Now and others like that but don't have access because of Cox (no fault of Roku). I am currently reformatting my movie ISO files into .mp4 containers so that I can stream directly from the Plex channel. The headphone works well and will certainly be put to use while working out on the elliptical. Never have any buffering issues as it is connected via the Ethernet option. Easy to install and works with my Logitech remote control. Just bought another for a Christmas gift.  Love it!!! 

Question: How is the quality of the interface?
