I have the Fetch TV through Optus, love the functionality - pausing live tv is great, as the large storage. It even has team tags for the footy, so I set it up to record all Richmond games automatically. We use it exclusively, and it has the built in Netflix, Stan, youtube apps as well as all the catch up channels.
The only downside was that I did have two previous gen boxes die on me though while attempting software updates, resulting in complete losses of all recordings and replacements. So far the new generation machine hasn't had any problems though.
