Yea, I tried that with a first-gen PI and decided it wasn't fast enough, but I imagine the current-gen ones would be. It also didn't seem quite flexible enough

Yea, I tried that with a first-gen PI and decided it wasn't fast enough, but I imagine the current-gen ones would be. It also didn't seem quite flexible enough, though - I do a lot of browser-based stuff (Youtube, Netflix, Plex, PBS Video, etc.) And I have a blu-ray drive connected - I usually just rip CDs and movies to my plex server as soon as I buy them, but occasionally I want to play something right away. And, lastly, I occasionally just use the TV computer to look up random things on the internet. So, I think I'm stuck with a "real" computer for the time-being (meaning a desktop OS and browser, mostly). A Pi with a regular Raspbian install would probably work, but I've got everything set up and working well at this point, so no reason to change it.
