An interesting read, but still pretty poor advice.
Whenever someone thinks "Oh, I might try my hand at [insert hobby here]" it doesn't mean that they should jump to the top-of-the-line equipment for that hobby, because they might want to upgrade later.
I don't know of too many 17 year-olds being advised to get 911s as their first car, despite the fact that they will undoubtedly, at some point, replace the old banger they do buy as their first car.
