Personally wouldn't try to do it all with one computer. Get a Roku, Android, or cheap computer media player and install Kodi on that. Have Kodi installed on an AppleTV and watch a 65 monitor with it.

Use a laptop, big external monitor, keyboard, and mouse for my computer. My old eyes like reading bigger on the big monitor (set to a lower resolution so it magnifies everything), and the regular keyboard/mouse is nice.

Have tried using a tablet and found myself going to the computer when I need to type. And that includes emails, forums, and URLs.
