The key change was the addition of copper strips to the metamaterial that shields an object from incoming light to create a better material, couple with a slight change in its orientation to solve a problem caused by dividing the metamaterial of the cloaking device into quadrants.
The orientation sensor automatically adjusts between portrait and landscape mode in most applications when the device is tilted, and the 2-Axis Accelerometer is great for controlling games that need simultaneous steering and acceleration.
The chromed plastic volume rocker, power button and screen orientation lock switch nestled in the plastic radio reception strip at the top of the device are decidedly less luxurious, however -- the travel of each was shallow, and the finish on the plastic appeared a bit cheap to our eyes.
