Out of curiosity, what exactly is the difference between a smartphone and a laptop wannabe? What is it that separates the Nokia 'smartphones' from an iPhone\Droid\HTC Touch?
The iPhone is as good of phone as any; it's tap to unlock and another tap to bring up your contacts; voice quality is as good or better then most phones, the calling features are excellent, and the visual voicemail is a step above most voicemail systems. In short, it does its job as a phone - no big drawbacks or huge advantages.
The problem with the iPhone and other phones using a similar calling system like the G1, Droid, Devour etc. etc. is the form factor. For someone who wants a basic phone, a small flip with a small screen is perfect. You have to baby a smartphone; the screen cracks easily, and the large form factor is bulky and inconvenient. Yet it's the price paid for having the features in addition to the phone.
Also, it's rather ironic that not 5 minutes before reading this I was browsing Gizmodo and noticed this article on the front page about nokia's 'flagship' smartphone. It's worth a read.
