Tag / world thinnest laptop

I admit this is pretty cool. It’s amazing they can fit the components into such a thin case, but my question is why? I don’t necessarily want a laptop that’s a couple of pieces of paper thick. I need to see these things proven before I’m sold. Do they overheat? Are they flimsy? Do they feel cheaply made? What kind of performance do you get? How thin is too thin?
