You wouldn't call your car a mobile air conditioner. You'd never refer to your microwave oven as a digital clock with heating ability or your PC as a Skype box. So why on earth do you still call your pocket computer a "smartphone?"
According to a recent study by UK Carrier O2, typical smartphone users spend 128 minutes a day actively interacting with their devices, but only 12 of those minutes involve voice calls, with the rest of the time split between emailing, text messaging, social networking and consuming on-device content apps. So you need to call that item in your hand a "pocket computer," "a communicator" or something else that reflects its primary purpose.
