Well, this depends.
Here's how a user put it: "I have to admit being a bit baffled by how nobody else seems to have done what Apple did with the Macbook Air - even several years after the first release, the other notebook vendors continue to push those ugly and clunky things. Yes, there are vendors that have tried to emulate it, but usually pretty badly. I don't think I'm unusual in preferring my laptop to be thin and light. (...) A notebook that weighs more than a kilo is simply not a good thing (yeah, I’m using the smaller 11″ macbook air, and I think weight could still be improved on, but at least it’s very close to the magical 1kg limit)." - Linus Torvalds
(Later he stopped using Apple laptops for the even lighter/thinner chromebooks).
