Laptops have terrible ergonomics. If you want to have the (small) screen at eye level, then the keyboard is not at a good height. If the keyboard is at the right height, then you have to look downwards to look at the screen.

At work, I have a laptop which is attached to a docking station which has a proper keybaord and two monitors connected to it. I almost never take it out of the docking station. I asked for a desktop but the official policy is to only hand people laptops.
