that is, iPhone 4 is 6 months old and in another 6 months its successor will usurp it. I have to say I can't believe I've had mine for 6 months. After that long I usually notice the problems and irritations of a device, but the iPhone 4 hasn't aged. Neither is it showing the wear of a lot of use, nor does it seem worse by comparison to newer technology. I may later regret claiming this, but the form factor is timeless. Until the base materials are altered from glass and steel, perhaps to carbon fiber, I can imagine only subtle refinements to the design. I wonder if another company can challenge Apple's superb hardware and software in the next 6 months. After that, I wonder how Apple will develop the iPhone.
