Everything's worse
You could publish a fake review now, then we could all vent our spleen about how it's a backward step, not as good as the 3G, etc. I hear that the r.f. reception will be worse (I made that bit up - see how easy it is).
I'd feel better getting it all out of my system now, rather that when the kids are back at school and the stress levels of the school run, homework, sports kit, etc coupled with a new iPhone review could just kill me. Does it come with a defibrillator app?
