Have iPhone, download lightsaber app. It's almost a pre-requisite for iPhone owners. From next month you'll need a new saber app though—the Bluetooth-enabled Lightsaber Duel which pairs with other iPhone users for proper dueling sessions.
One night waiting outside of a venue waiting for a concert, days after the app store opened, I saw two strangers having a a "lightsaber duel" with their iPhones. Not just waving the phones but spinning around and chasing each other. Then they brokedown laughing and high-fived each other.
That was the day I began to hate the iPhone as hipster crap. I saw it again many times in the following weeks and described the phenomenon as an "iPhone circle-jerk" and vowed never to be like that.
The iPhone can be a great tool but if you download this app PLEASE never use it as a reason why the "iPhone Rulz!" The rest of us think you look like idiots waving phones around like that. Worse than the guys with bluetooth headsets that walk around like they're shouting at invisible people.
