And the fact that there is no annoying fan noise ever is just priceless.

With the way most consumer laptops have their fan curves set, you open a new web page and get an annoying ramp up. It is not just a hardware thing, but mostly a self inflicted wound of having a fan curve that is way too aggressive.

If it's not aggressive then quickly laptop will be too hot to touch. For instance, I did tune the fan on my friend's laptop so that it wouldn't be waking up everyone for light browsing, but then it was getting uncomfortably hot. None of such issues on Macs.
