Crash

The iPhone makes a great gaming device. With it's accelerometer, you can use the device itself to "steer" in games like Cro-Mag Rally, a game that shows off the capabilitiies of the iPhone very well.

Unfortunately, it also shows off another side of the iPhone - that it's essentially a computer, and prone to crash from time to time. Neat though Cro-Mag is as a game, every time I've run it, my iPhone has decided to lock up. Quite why this is the case I'm unsure at the moment, which is a shame, because it shows a real "wow" factor to the device.
