Contrary to the rants of Luddites worldwide, technology aims to make life easier. From toasters to cars to mechanical pencils, technology helps us do things with greater ease.
Yet for every useful advance comes a set of complications. An improperly utilised toaster can burn down a house, a bad driver can wreck a car, and a mechanical pencil can - well, we all know what evils lie in wait there.
That same lesson applies to iPhone games that make use of the device's accelerometer. At best, it makes things easier, and at worst it turns the game into a battle.
