I don't think the change from x86 to ARM from Apple will have the ripple effect some seems to think. In the history of Apple Computers, Apple used PowerPC architecture for a really long time. Before making the change to x86. Yet at the time PCs were already on x86 for a full decade. IMO AMD and Intel are still set for a long time. As ARM processors catch up to x86. Although ARM processors have made pretty good leaps in the last 5 years. Their progress seems to have slowed quite a bit. The changes are no longer as radical from generation to generation.
