" However, you may find the placement of the Ctrl and Fn keys in Lenovo notebooks, for example, different from other notebooks."
There are more than just those keys, there is also the end, home, pg up and page down keys along side many other keys that can be behind a fn key instead of a dedicated key. It makes a ton of difference.
"The trackpad controls the mouse pointer, and it is important that it offers a smooth navigation experience. Ensure that the laptop you select has a trackpad that is large, is responsive, allows for gliding your fingers without much friction, and has easily clickable buttons. While MacBooks have long held the distinction of sporting the best trackpads in the industry, modern Windows laptops come with Windows Precision trackpads"
Macbooks have TERRIBLE trackpads, just because most modern windows laptops have worse doesn't make them any better. I'd even take a smaller trackpad if it were like the old kinds and not these new ones. If you use your laptop trackpad for a long time, these new trackpads are nothing more than quick way to strain your fingers and wrist. They are simply trying to cut costs and go around it with software.

"The last thing you would want to have are fried thighs when using your laptop. It is important that the laptop does not have high surface temperatures. Laptops usually get warm near the middle and upper keyboard deck under load as that is where the CPU and GPU — the two most heat producing components — are located. Even under load, the temperatures in these areas should be manageable. The area near the trackpad and rear bottom half should be absolutely cool and as close to the room temperature as possible."
That's only half of it, you are also killing the lifespan of your components. Especially the battery. Even more so since now removable batteries are harder to find.
