It's like someone who buys a Honda going to a guy who bought a Ferrari and saying it's a stupid move because it doesn't have MP3, power seats (many don't), bluetooth etc.
Of course there are phones that have more functions but, as someone said, this is 04 model and today costs pretty much the same, and people are buying it. They don't have to release new models every few months, but every 2-3 years. It's quality, craftsmanship, design.
As far as comparing it to an iPhone, again, it's like Honda vs. Ferrari. This is especially true when it comes to durability, try dropping an iPhone, or running it over with a car.. (no DO NOT try it as it WILL destroy it).
