Some have said that the iPhone 4s in not a major upgrade over the iPhone 4. Some were expecting a form-factor change and maybe a larger screen. I say Apple did the right thing. They took an exceptional device and made it fantastic. The so-called under the hood improvements are substantial and the fact that the form factor didn't change is a bonus for those of us who are comfortable with the current design. The new iPhone 4s is really an all-new phone but with the added benefit of keeping a beloved figure.
