You want a 6 inch device to shoot 4k videos then you're clearly not in the market for the iPhone.If it's the same bleeding 4 inch screen, I hope someone in the crowd yells out "BOOOO". I would if I were there. Guess I'll know if I'm coming out of pocket for a $700 Note 3 in a few hours.
Just found out today that the Note 3 can shoot 4k video, too. More and more I'm being pushed to getting my first Android phone.
Right now, there's still a lot of people who like their phone to fit in their pocket and have no use for limited 4K video shooting capabilities, and I, for one, I'm happy that I still have the choice to get a "smaller" device (I was perfectly fine with the iPhone 4's 3.5" screen).
