Mostly the physical design (and the culture and market decisions behind it). The cheap plastic mentioned in the article that attracts thumbprints. The lack of attention to things like coil whine. The screen flicker, fan noise, random wake ups, etc.

Are you aware that there are countless different designs on the market? Try a nice model some day.

I'm well aware. I'm also aware that the nice models are both few and far between and (the few that exist) cost the same (or more) than a Mac laptop.

Here's what Linus (or a certain OS fame) wrote about the situation:

"I’m 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".

That was back 3 years ago. Since then he also adopted the Chromebook, but the general complaint still stands.
