It ain't sexy, man.

Hey, gentlemen, I understand that the Gameboy Advance is really a great product - we can play Super Mario and F-Zero anywhere we like. But please don't play it when you are travelling on the MTR. It just makes you look pathetically ridiculous.

Here is a typical scenario:
A man in his forties entered the cabin and leaned on the grab bar. Then he hold the newspaper between his thighs, took out his gameboy from his pocket and started to play. Judging from the way he pressed the buttons, one could tell that he was a monkey- he simply pressed too hard - that would lower his speed and flexibility. He concentrated so much that he nearly fell when the train halted. Hell, he even didn't notice that people on the train were looking at him.

Gentlemen, if you want to play games on the MTR, get a palm. Nobody knows what you are doing with your palms. People would think that you are utilizing your precious time to re-arrange your schedule or read e-books. Moreover, there are games for adults on palm!
