Logged in just to comment on this without being taken as a shill. (seriously - check my karma.) In much the same way that CryptoCat’s dev team have realized that usability is a core feature of security, and not a nice-to-have, so too has the Plex team made usability a core feature of their product in ways the XBMC team was late to implement.
Plex’s lack of extensibility, scraper support, and local storage support drive me up a goddamn tree, but Plex works and XBMC doesn’t. I’m not a linux person, but I am a nerd - code is not my day job, but I’m teaching myself at night. Sweet baby Jesus, I tried XBMC so many freaking times that eventually I just gave up. And when my certified-Mac-tech friend showed me this miraculous XBMC fork that worked on OSX, with his remote control, and without fucking around, I spent a few years not looking back. I think I got myself banned from the TVDB trying to get Plex to identify shows properly, but it offered me the ability to play back home videos and fansubbed anime on the TV when I could not afford a dedicated HTPC - and that included salvage, scrounged laptops, and selling my body for transistors. (it was a rough patch in my life)
Ironically, I more or less quit watching even foreign television about when I got Plex to sit down and play nice and XBMC became Kodi and began to make setup less infuriating for people who didn’t hack C in their spare time.
More ironically - nay, infuriatingly - I spent most of my free time a couple weeks ago trying to sideload Kodi on my FireTV to try it out, and only found out there was an official app for it after the app was taken down. Way to piss in my cheerios, Bezos. :(
