What do i use Fire TV w/Kodi for?
For starters I do not have a Smart TV, because years ago befure the term was common, I made my own smart tv by first adding Roku, the WDTV media player, Chromecast and lastly, Fire TV I shared drives in my network to access media files to play and eventually wrapped all the media files into a WD My Cloud NAS.
I can play all this media on most any of the devices, but always use our favorite one (best interface, easiest to use, etc) for what we want to enjoy. Most time the WDTV plays our music, because it can easily play from playlists, for Netflix, we use Roku. For watching our stored DVD movies on TV and tablets we use the WDTV to stream from NAS. The FireTV w/Kodi is a good substitute for the WDTV and Roku, because the WDTV is not made anymore, so when I needed another one, I got a Fire TV instead and installed Kodi on all Fire TVs. Also have a Fire TV for vacations and a wireless hard drive w/media files so music/movies can be played from HD to Fire TV and onto TV or iPads.
So, I don't need "no stinkin' Smart TV", because I have a smart media center already.
