Don't all the XBMC/Kodi-likes suffer from having poor support for mainstream content providers. I've looked a few times over the years, and add-ons for Netflix, YouTube, iPlayer, etc. were slow and terrible for discovery. If you knew the exact name of what you wanted to watch they were just about ok, but beyond that they just didn't fit the paradigm of something that was designed for browsing static libraries of content.

Isn't the whole premise of Roku that it does this well with cheap hardware?
