How can this phone possibly perform better than a 635 when it uses the same processor and graphics chip driving a higher resolution display? The only thing I can see that might make this possible is Denim... which will come to the 630/635 as well.
I have three lines with AT&T... one of the users is interested in the 830, but he currently uses an 820. I wish I could know how big of a step down it will be, especially for games. He's not overly concerned about technical specs, but he will definitely notice if it doesn't play his games as well.
I really would have felt so much better if they had used a Snapdragon 600. I just don't understand how they justify this model having the same processor as the 730 and 630.
(Incidentally, the other two users including myself are waiting for MS to release a 1030)
