I'd love to not have to have a cable source for shows, but until the content producers get their heads out of their asses, I still can't watch what I want from the Netflix/Hulu combination. I also hate having to switch apps to use those, but such is life it seems.
It's FAR from ideal, but it's the most polished turd I can find. It's the only thing I know of that (barely) passes the wife test and does the things I need.
Also - how is Roku in terms of a 3rd-party app ecosystem? That is another essential in my books.
Roku has a better app ecosystem than Google TV, more video channels in particular.
If you have a GoogleTv, there's an App to view plex content in the Play store.
As an added bonus, it's possible to run sickbeard / couchpotato / sabnzbd on a Synology as well, so it becomes a set and forget experience.
Lets me connect over cifs/nfs, which is my preferred way to connect to my Synology DS410.
