Did the preorder today at Best Buy Mobile for the Maxx. Not sure when they will be shipping, but i have till it ships and then 15 days after to trade it in for the GS4. Seems like the GS4's camera may be a little better, better development options on the GS4, uSD card, removable battery, IR remote and all the gimmicky features that somewhat work. Just curious how many here may have had a GS4 and now own the Maxx. Why you made the switch or comments on things the Maxx does better. The guy at Best Buy Mobile almost talked me out of preordering the Maxx and couldnt be more happy with his GS4. No issues with battery life, sluggisness or signal strength. Thought i had my mind made up between these 2 phones but?? Guess ill give the Maxx a shot, keep reading the forums and reviews and decide whether ill go for the GS4.
