Also, what about the new iMac case being two pieces of black glass (front and back) with a band of aluminum sandwiched between like the iPhone 4?
In retrospect, it would have been better if the new iPhone had been aluminum unibody like the iMac or iPad than having a glass back, which has to be thicker than aluminum to be strong and which serves no purpose anyway.
The only justifiable reason for the iPhone having a glass back would have been if they had put the antenna inside the phone, because the signal could penetrate it more easily than metal. But, no, they had to put the antenna on the outside where any 10-year old who ever used a walkie-talkie could have told them the signal would be interfered with by touching it.
Although I waited expectantly for an iPhone 4, I have now decided to pass. It is the Vista of smartphones.
