Wired and Bubblegeneration have the most insightful commentary on Apple's decision to switch to Intel processors.

Strategies that acknowledge that digital reproduction and modification is easy and inevitable, and work with that will be more productive than those that waste energy fighting against it. Can Apple be a platform for all players, or have they chosen the losing side?
