I'm sure it's a great phone but how is it night and day better? Honest question looking for more than a spec breakdown and more in terms of usability.
Agree! Will it be faster, yes. But how will that help me out? Will it send my text messages out faster? Not that I could notice. Will it stream Netflix? As of now, no. Will it make my Sirius streaming sound better? Probably not since I have no problem doing that. Will surfing the net be faster? Yes, if I am connected to the network, however, most of the time I am connected to wifi, so I won't notice any improvement. Will the screen be better? Yes, but probably not drastically better than the retina display. Will it make the music I have on the phone sound better than the iphone? Probably not. Will it have better signal strength? Probably, but I don't have that problem. Will the sound quality be better when talking on the phone? Maybe, maybe not. Will the battery life be better? No.
So in general, it will have a faster processor. For most people that is not a big issue, since most smartphone users dont even push the current phones they have.
It comes down to what you want and need. Everyone is different. It definately will be the newest and best device out there, but not eveyone prefers the newest and best, if what they currently have offers them everything they want and need.
