I tried a couple of videos... Just like Zune HD ... New ipod touch and old... iPhone 3GS can both play HD Videos... iPhone its old but iPod touch i haven't seen anyone talking about it... I tested all sort of videos and its stable now in iPhone at 3.0 it was very buggy.... Now it works even though the screen is not capable of FULL HD but it defenately support HD now! I am sure an accesory is on the way to output HD vidoe on HD Tv... That will close another advantage door for Zune Hd... What you guys think? Just a basic test :- Go to podcasts in itunes store ... Download Something with HD! like Cnet Top5 HD. The quality has a big difference.... I think itunes wont sync HD files though... Not sure about this.
