>> So while a consumer photographer, may use their phone or compact or all-in-one camera, enthusiast photographer will probably spend $3000 - $5000 in camera gear.

It's interesting that you chose photographers as the example here. In many cases that I've seen, enthusiast photographers spend much more than professional photographers on their gear because the photographers make their money with their gear and therefore need to justify it, while the enthusiasts are often tech people, successful doctors, etc., who spend lots and lots on money on their hobbies...

In any case, your point stands, that "enthusiast" computer users would easily spend $3-4K or more on gear to play games, train models, etc.
