Here with my daughter, she is paying for her own phone upgrade and is choosing between an iPhone 4S or the iPhone 5. There is a noticeable difference in thickness - but didn't see one in the height or width.
Maybe later, I am just taking advantage of being here so I can upgrade my phone OS and grab someone if it goes south on me.
It's dangerous to post from their sample laptops - I so WANT ONE now. I know this is how you taste the kool-aid and then figure out you really do like the fruit punch over the grape.
