They are both too big for me. The only way I will consider an ip6 is if it still has a 3mm audio jack! Beyond that the 5.5 will never be an option for me, so I have to hope that the 4.7 is tolerable but it will be unfortunate because even if it ends up being the best iPhone I have owned I will never be truly happy unless my phone is under 4.5".
I also HATE these gold colored phones. Everyone made fun of apple (and rightfully so) for the ip5s in gold but then every major handset maker turned around and made one as well. Gaudy.
Even though I'd be sorely tempted to jump into a 5.5" model, I think I'd have to physically try one out before I actually bought one as it may be just too darned big. However, my 3 year old iPhone 4 (notice there's no S) is definitely due for an upgrade.
Also not such a fan of the "gold lamé" look. Brushed metal or black, white even, but no gold.
The main thing that Apple needs to redesign and revamp is their prices. It doesn't matter how elegant they are if they're too expensive.
I really hope these are some kind of super-early prototype, as these phones look like ass.
Perhaps they've got a coil wrapped around Steve Job's grave so they can generate electricity from how fast he's spinning in it...
