I am horribly addicted just like all of the other 200 million sheep out there with iPhones and iPods and iPads. My current favorite timesuck involves RISK-like games on the iPhone/iPad, particularly Lux. This game runs on Mac and PC too, but it just feels like a natural on a touchscreen. I've managed to play so much that I'm an equal match for the most difficult AI that they've come up with. What's your poison?
