I was at the Mac Store with my Pro 15 because it was making a scratchy noise. I started talking with another customer with same Pro 15. I explained what I used my computer for: almost always for word processing and internet, a little photography, even less video editing. He said, 'you bought yourself a Ferrari to drive at 20 miles an hour; it's nice to have a Ferrari if you have the money, but do you really need it?'. He was right damn it! He has his for 3D models of properties, pixel hungry plans.
