Hey, please remember I was teasing -- secretly I have the same concerns as you, I'm just a lot more shy about sharing them. And the iPhone, truthfully if people can't talk about whatever phone they want here then something's wrong. But you also have to show your team colors and trash-talk the competition.
I had started out looking at the S3, and wouldn't let myself even glance at the S4, let alone pick one up and try it. Eventually my will-power broke down and now I'm watching the price on Amazon daily (I forgot that Best Buy aggressively price-matches now too). I'd be all over the S4 if (a) my Droid 3 hadn't suddenly gotten a second wind and started working again, and (b) Verizon hadn't announced that they're selling the HTC One. Right now I'm split between the two phones. What it will come down to is the price of each phone once the One's released, and whether I decide I want the amazing software and camera on the S4 (plus the removable battery and card slot), or the clean metal unibody on the One.
Please keep the forum posted on what you end up doing.
