World's Biggest Handphone

Yesterday, while Alex and I were walking past Forum Galleria, he nudged me and whispered, "World's biggest handphone!" I looked around to see what he was talking about. Sitting on some steps outside Forum was a Caucasian man using his laptop as a telephone. He would lift his laptop so that he could speak into the built-in microphone, and then move it so as to bring the built-in speaker to his right ear. He kept doing this throughout the conversation, making a kind of swinging motion, between ear and mouth with his regular-sized laptop. I'm guessing he couldn't find his plug-in headset with microphone. :)
