It makes sense if you use the laptop as a desktop - plugging it to a bigger monitor with an external keyboard and mouse. Otherwise it's hard to have good ergonomic with a laptop and you can't work long hours on it without developing some body pain.

What kind of pains does a laptop cause that you wouldn't also experience on a desktop?

Forward head, rounded shoulders.

I don’t use my laptop in any of those places because my desktop setup isn’t there. Laptop keyboards are awful to type on, why put yourself through that?

I’d rather get my work done at the desk and then enjoy my hammock or couch without the computer, preferably with a good book.

If I'm using it in the kitchen, it's probably to read a recipe or watch a video, neither of which is a keyboard-intensive task.
