Oh yeah it’s totally an appliance OS built around Kodi and not a general purpose OS. I do use it to watch YouTube though. I’ll “send to Kodi” from my phone and it plays on the TV. I use a full desktop computer for all the other stuff you mentioned. I only brought up Kodi on the raspi because this meme specifically calls out videos, which do work quite well (as long as it isn’t a vc1 encode apparently).
I would like to take this opportunity to remind everyone that even the United States FBI recommended using ad blocking extensions to protect yourself online.
