By far the two most frustrating aspects being the forced updates (which were often more buggy or broke features) and the lockups while in sleep. There was nothing more annoying than having to get up and hard reboot the thing every time I wanted to watch something.

Once the Pi and raspbmc became a viable alternative I quickly replaced my boxee boxes because, while not bug free by any means, they're much closer to "just working" than the boxee box ever was.

The one good thing I can say about the boxee box, though, is that its remote was a real treat. That thing worked like a charm.
