I don't think that's necessarily true. Many of us who share progressive values and are trying to become less materialistic, live simpler and more fulfilling lives, reject consumerism, are nevertheless excited about this new device.
So many of us see the iPhone as the first of a new generation of devices that are become ubiquitous anyway. But it actually frees us, to a greater extent, from the dictates of a particular carrier's choices. Let's face it -- sooner or later, the vast majority of us will be dependent on what we now call a "cell phone," as well as email and "texting," for interpersonal communications. We should welcome a new device that lets us do these things with greater ease and freedom. In a small way, it's a step toward greater individual autonomy.
I am not an Apple shill or employee or other promoter; actually, I am a law professor, and in my extra time I do some litigation, most of it on behalf of ordinary people against the moneyed interests. I do use Macintosh computers, but as yet I don't have an iPod or any of the other similar toys. I didn't buy an iPhone yet, and I probably won't for a few more months. Maybe, if it works as well as the hype suggests, I'll hint that it might make a nice Christmas/birthday/anniversary present (at least for part of the cost).
Is the iPhone expensive? Yes. But if you analyze the TCO (total cost of ownership) and factor in the greater functionality, for many of us it becomes a choice that has sufficient value to justify that cost. And if you think that ordinary working people, even those at the lower end of the ladder, can't afford these things, look around. Just as almost everyone has a telephone and a television and some form of computer access, we are rapidly heading toward a time when almost everyone will have a cell phone and some kind of portable entertainment device. I expect that, over time, the price will come down, and that even those at the lower end of the ladder will find it worth having either the iPhone or some similar device.
So before you dismiss the iPhone as just another expensive, unnecessary toy, take a closer look at what it does and how it does it. You might change your mind.
