I did a build from their repo and pushed it to the Apple TV, just to try out the rewrite changes. It's considerably improved, and plenty nice for my purposes. I didn't feel like I had to, though. I'll delete it and use the app store version when they cut a release.

I think a lot of people are doing stuff that's well beyond what I use it for. I just have my blurays and dvds on there, so it's possible I don't know I'm missing some important stuff that other people need.
