For young people out there, it is better to build a desktop gig instead of a laptop. You can't change much in a laptop, unless it is some legacy laptops, but definitely not a Mac. Parents should help their kids to build a 16GB Linux gig. It's going to be more expensive than $599 nowadays due to the price of everything, but still, it is very expansible, and the kid can earn $$ and decide which parts he wants to upgrade.

BTW a laptop is definitely the only choice if the kid wants mobility, though.
