I agree. It needs to be so small that I hardly know that it's in my pocket, but big enough to have a useable screen. Apple have judged this balance perfectly and it got even better when the made the whole thing thinner with the iPhone 4.
I'm nervous about any antenna redesign because I really hope that they find a way to optimise the existing iPhone 4 "antenna on the outside" concept and don't feel the need to revert back to an internal antenna that would presumably bump up the thickness again.

Me too I hope they find a way to "cover" the antenna maybe with a clear coating or something like that. About the screen I feel most companies try to use that as a hook so they can say "We have something bigger than the iPhone". But in the end the iPhones screen size is just perfect for everything.
