I fully devote to the iPhone and other Apple devices. That said, give Credit to where it's due, Samsung's Galaxy line has its advantages over the iPhone in terms of hardware and software as well. In some respects, the iPhone is stagnant in terms of hardware design, where as the Galaxy has been fairly dynamic this last year, aside from the Note debacle.
The Galaxy has its pitfalls, but the iPhone is far from leaps and bounds over the Galaxy. Speed and fluidity of the OS is noticeable, but that doesn't change a three-year design with incremental features updates (Speakers, haptic home button, etc). I'm not degrading the iPhone, but those are obvious reasons I stated.
