I am calm. Why do you keep asking to be calm ? A tantrum ? Next you'll be telling us you're a master at detecting sarcasm in written posts ?

Maybe you're stressing out over this, but if you would read and understand my posts, you'd know that there's nothing for you to even argue here.
You say 720p is fine. That's perfect! A 1080p output capable AppleTV does not impact you since it plays 720p perfectly.
I know it's "hugely" significant, I didn't say it wasn't. I questionned the 54 Mbps number. That number in particular, not any kind of bitrate.
You should really work on your reading comprehension. First you come in with downloads, then downloads again and now this. You turn "Where did 54 Mbps come from ?" into "Bitrates are insignificant...".
Seriously. Either read and understand my posts or don't respond. And stop feeling threatened because someone questions Apple's decision.
