N97 mini vs iPod Touch (screen and software)
I can’t talk about the call quality of the iPhone, but I can compare it to some features of the iPod Touch.
First, there is a lot more software available, a second difference is the screen. The screen of the iPod is capacitive. So the device reacts when you touch it with your body and create an electrostatic field. In this case, you don’t have to press on the screen but just make contact with your fingers.
The third big difference is that the software of the iPod is actually made to ‘touch’, and you don’t have to double-click an item to select it in some cases.
I prefer a resistive screen when you have to press on ‘buttons’, but when you have to scroll through items, a capacitive screen is an advantage. As well the kinetic scrolling* (I think it’s integrated afterwards in S60) looks much smoother on the iPod.
* Clearance of some Jargon
Kinetic scrolling: Scrolling through items by sliding the whole menu up or down (just like an iPhone/iPod Touch, to be clear 
)
Resistive screen: A screen u have to ‘press in’. So you can use any object to operate the phone.
Capacitive screen: A screen operated by touching it with a conductor (The human body for ex).
