EA's Need for Speed Shift was one of the first games showed off for the iPad. It's also a game that helps you look like an idiot in public as you flip your device back and forth like a virtual steering wheel.
The iPad version of the game adds a few bells and whistles. The most noticeable being better textures and more detail on cars (both inside and out). There are also eight more cars in the iPad version, as well as a more realistic feeling of acceleration as you zoom around the track.
