For me, the iPhone is primarily a money-making machine for Apple.
As a product I don't grasp it, I use one every now and then, but I just don't see what's so great about it. Just a few days ago I get frustrated as I could not change equalizer settings ad-hoc while listening to youtube or "ipod" - due to lack of multitasking I could not go to the sound prefs where equalizer settings are, without the ipod/browser apps exiting - also there are no manual settings, just a long list of predefined settings with more or less meaningless names - ridiculous. The mail reader is just rubbish compared to what I'm used to on phone, and third party IbisMail wasn't that much better. The input method of typing with finger on a virtual keyboard is just too slow and clumsy, every time I use it I long back to stylus on SE phones, where I can type without even looking at the device. And how do I change to a different charset anyways? And the list of other obvious shortcomings is long and well known.
