Here's a quick S4 recap stat-run down:
21.7" screen
24-core processor
SUPERINCREDIBLEAMAZINGAMOLED screen
A bunch of random useless features that have no actual application for every day use that Samsung will use to say that "Apple doesn't have these things"
Cheap plastic body
Terrible battery life
Glitchy, laggy TouchWiz
Android 4.1 Jelly Bean
The Fandroids will buy it, say that it makes them "smarter than iOS fans", they're "power users", Samsung will make some more commercials about how it is better than the iPhone, and they will continue to bring up the misnomer that Apple is losing it and Samsung, with all its innovation, is the wave of the future. Meanwhile Samsung continues to blatantly copy and rip the iPhone while they try to get a peek at iOS source code in an attempt to rip off Apple.
The 5 is great.
