Nice, I have been looking at that for a bit now.
I like my jailbroken ATVs, but I feel like it needs more.
My ATV's weren't jailbroken. I ended up selling 2 of them for $405 total. Ended up buying a Western Digital TV Play which works fine for it's intended purpose. I use it to play my extended movie collection from a connected HD on my living room TV. The app selection is pretty poor though. For $65 I can't really complain.
The Roku 3 on the other hand has a ton of apps, and the playback quality is at least as good as the ATV 3. So far I'm very pleased
One other thing, it had a headphone jack right on the remote which works flawlessly!
