i went to the AT&T store last week and put their balls in a vice and they gave me an upgrade to the Galaxy S4 even though my contract isn't due til like march lopl
holy smokes is the S4 fast and big. the S4's size makes my S2 seem as small as my Zune HD did when i first got my S2. absolutely loving the S4, there's literally nothing bad i can think of about it.
At the moment it's basically a tie between the HTC One and the Galaxy S4.
But in reality the Nexus 4 is the best bang for buck.
btw in terms of pricing, as far as i've seen, some places like costco or other wireless retailers have AT&T's Galaxy S4 at $149.99 w/ 2 year contract
