Well, then by that logic, since desktop computing tasks don’t really use all that ram: we shouldn’t need more than 8GB in a desktop ever.

if this is the logic we're using, then we shouldn't have phones at all. Since clearly they do nothing more than a computer. Or we shouldn't have desktops/laptops at all. Because clearly they do nothing more than a phone.

I understand that phones are more capable, my point is that they have no reason to be more capable. 99% of what you do on a phone is going to be the same whether you spend 200 dollars on it, or 2000.
