Apple isn't selling computers anymore, they are selling toys. Macs are a great design but they are no longer designed for work.
10 years ago, you needed a Mac Pro to really do professional 2D design and photo work right. Today, you only need a laptop + secondary display. So it's actually the opposite of what you're implying: the power that many pros need has migrated down the product line due to the vast increases in processing performance per watt. The Mac Pros of today are for much heavier lifting that running the Adobe Creative Suite etc.
