Feels like a toy? The phone feels like it's made out of carbon fiber! It's deceivingly light...i picked it up for the first time expecting it to feel weighted at least similarly to the 4S and it was like a whole new world. To me the phone feels solid and efficient, it doesn't feel plastic and light, it feels like the Macbook Air to me, scary light...like "how the hell did they do this?" light.
To me, the phones rocking the plastic shells feel like toys...sure they're light, but they also feel extraordinarily cheap (even the 3G and 3GS felt cheap to me, and they were whales compared to this phone, it was just that plastic outer shell).
I can totally get this is going to be bizarre to some people, my wife personally said the same thing but more as a question..."I'm afraid I'm going to break it" was her exact words. I get that, when you associate the light chassis with the fragility, i can understand why a person might be thrown off about it. But to be honest, looking at many of the tests online thus far, dropping the phone and impacting it with various things, it seems pretty damn tough!
