I want to know the answer to the following question:
What is the only mainstream computer platform to successfully transition to a new CPU architecture?
All the background I'm provided with is that "Starting with the then-new iMac G5, released in October 2005, Apple started to include built-in iSight cameras on appropriate models, and a media center interface called Front Row that can be operated by an Apple Remote or keyboard for accessing media stored on the computer.". Is that enough to answer the question?
Answer: no
