The Samsung Mobile Galaxy S4 is at Verizon Wireless stores starting today. I picked one up and immediately shot a photo comparison.
First gut feel? I like the thing better than HTC One (which has really crappy reception, lots of dropped calls, damn do I hate AT&T) and even my iPhone 5 (which is nicer in areas, but I can no longer giveup the SwiftKey keyboard, which makes me much faster than Apple's keyboard does).
Highly recommended. Apple has been passed in a lot of ways. It really does pain me to say that (Apple is my hometown company, I grew up in Cupertino and have always been a fan, even waiting overnight to buy several of its products).
