21 guilty pleasures for geeks

11. Dangling a Bluetooth headset from your ear and pretending you're Buck Rogers
People called you an idiot when you wore one in the street, so you don't do that any more. But stealthily hidden away in your car - or better yet, at home - you stand puff-chested and proud of the little black thing with the blue flashing light. I am important, it says, RESPECT ME. We do.

12. Waving your iPhone around like it's a lightsabre
Thanks to the Lightsaber Unleashed you can finally live out your Jedi fantasies par excellence. With the phone in your hand you twist, twirl, perform a 360-degree mid-air leap (OK, you're still working on that one) and marvel as your PhoneSaber crackles, cracks, slashes and vuuuummms. You have the cloak and beard to go with it and everything. Truly, the Force is with you. Just don't do it in public, OK?
