It seems to be a standing joke that you have to look like a dick whilst making a phone call on the Nokia N-Gage, unfortunately the truth is even worse.
If you see someone making a call on an N-Gage taco style remember one thing; the guy has actually chosen to look like a dick!
Did you know that a hands-free kit comes as standard equipment with an N-Gage? Or that Bluetooth the feature much touted for multi-player gaming, is also rather handy for use with a headset? Although admittedly a Bluetooth headset can make one look a little like Uhura from Star Trek!
