> You wouldn't notice it, the difference in weight between aluminum and titanium phone shell is negligible compared to the weight of the glass, battery, and PCBs combined. The previous iPhone Pro's have a stainless steel shell, not aluminum, and the ~30 gram difference is noticeable. Of course, they caused this problem themselves by using stainless steel rather than aluminum like the regular iPhones, but they are nonetheless solving a problem with the titanium frame.
