I have an iPod Touch, which is about 80% iPhone and it's a nice thing to have. I'm still pondering a full iPhone, but I'm waiting to see if the Pay As You Go option will be available. I'm not a heavy mobile phone user, so even the cheapest iPhone contract requires careful consideration.

That said, if the experience I am getting from the iPod Touch is anything to go by, the iPhone should really be on my wish list.
