I have this phone on order through Verizon. I thought it was going to have a 1.5Ghz dual processor? Reading these specs, they all say 1.4Ghz quad processor?
Regarding the processors, I don't think you or most people will notice much difference in the quad vs dual. The S4 has been getting strong praise and combine that with the 2GB of RAM and you can be it will surely fly.
