Finally had the chance to play with the S4 for at least an hour and a half at my local AT&T store. I am absolutely blown away. The screen is fabulous. Viewing angles are very nice. A big part of me was hanging on to the idea of the HTC One, and that was mostly due to my idea of the cheap plastic on the S4. However, the Samsung wizards have made a beautiful phone, that feels light yet solid, and also managed to fit a bigger screen in here without making it feel cramped. The speakers are just as nice, in my opinion as the HTC One. I'll avoid getting all review-y, until I get this phone later in the month. But this is an awesome phone, and I am definetly making the switch!
