I don't really care who makes my TV. I am a big fan of the Apple TV but I've also got an Xbox and a box for my incoming HD signal. The only thing I want for my TV I really care about (and unfortunately I was not able to find in any TV) is easy switching between my attached devices. I don't want to reach for my TV remote to switch HDMI inputs using a horrible menu. I just want to use my iPhone to start playing a movie over AirPlay and not care about what input my TV is set to. I just want to reach for my Xbox and start playing again without switching inputs, etc. The only reason I still have my TV remote is to switch inputs, every other device has it's own ways of control.
So if only Apple knows how to fix the HDMI switching problem (as the first in the world by my knowledge) I will buy their TV, for that reason alone.
