Because that just gives you the same crap, hardly even evolutionary. I'm sorry but you don't get it. Jobs was about large evolutionary steps if not revolutionary. You seem to want to keep status-quo.

WHole point of this tv is to remove all said "different boxes". Just stop and think about it. A TV that would NEVER need anything attached other than ethernet.
That won't work unless you only want all apple products. I have a ps3/wii others have DVD players. Say what you want about blu-ray but there is no streaming service that offers close to the quality that you can get on a disc right now. music is different because most people converted CD's to mp3 anyways so it was no different.
Streaming TV still has poor quality. People still own xbox/nintendo/etc and that won't be changing
