Skeptical about laptops

Even the lightest ones are too heavy. Ergonomically, how good can those keyboards be? There's no slope, and the relationship between the screen and the keyboard doesn't seem correct. If the keyboard is the correct height from the floor, the screen isn't quite right for viewing. Some keys are not in the accustomed places. The keys are not, in most instances, quite the size they're expected to be. The heat emanating is surprising, always. Somebody sells a gel cooling pad to be placed under a laptop. Or is "notebook" the preferred term these days?
