I don't have 4S because I see no reason, ditto for rumors for iPhone 5 even.
CPU? No, I don't find wait time on app/web loading to bother me.
GPU? No, Inifinity Blade, Dark Meadow :drool: already tons of fun.
BIGGER? No, I can easily use it one handed, thumb across screen, don't negatively impact this.
DISPLAY? No, current IPS/retina is brilliant.
BATT LIFE? No, I go all day as is with batt to spare, and even get a second day on the rare occasion I forget to charge on nightstand.
LTE? No, I get 3-5.9 mbps reliably (haven't broken 6, yet) on ATT 3G now, that's faster than standard DSL, on my freaking mobile phone. I have no lack of speed, not missing out on anything.
STORAGE? No, I have the 16GB variant with 8GB free.
Siri is a mild curiosity, to see if it transforms how I use my mobile, but it's not bothering me.
I'm not even excited about the iPhone 5. I could very easily holding onto iPhone 4 through 2013 or 2014 whenever Apple stops supporting it with updates.
