Yes, I'd rather carry a lighter laptop, but that's mostly because of all the other stuff I want to carry in my backpack (eg groceries). If walking "a few kilometres with a 3kg gaming laptop on your back" is a problem for you, you're rather out of shape.

This is disingenuous. It's not a problem, just less desirable.

I weekly carry about 10kg of groceries in my backpack about 2.5 km. Doesn't even register as anything exceptional.
