Those other parts of the laptop are cheap though. Sure not free, but chromebooks can be had new for just a few hundred $$$ (they don't need a fan either). If you want a fast laptop you need to spend a lot of money, but a fast laptop has the ability to have better RAM, SSDs and such than your phone because there is more space in that form factor and so if you want fast you are back to laptop while if you don't need fast your laptop is cheap.
