Drawbacks of the PowerPC Architecture
• High Power Consumption• Not suitable for use in laptops
• No backwards compatibility
• Improvement of the PowerPC was plateauing

Criticism to Apple’s Switch to Intel
• No backwards compatibility with older Apple software
• Less Computing Performance
• Fear of Intel taking over Apple software
• Intel’s Performance was Inferior
