Phones or bricks?
I just got the Verizon iPhone 4. I am veryy happy with it. Any larger and I would just use an iPad. Any larger and I am no so sure I would like it. The iPad is a good size for browsing the web. Any larger I would just use a laptop.
I’m not particularly interested in a larger iPhone either.
But I can say there are rumors that Apple is interested in eliminating the “home” button on the iPhone and the iPad. If that happens, the iPhone may not have to be bigger.
