I was around when laptops started entering the world.
Before laptops, only desktops were available, and a good number of American households did indeed have at least one desktop.
Of course, residential ownership of desktop computers came after computers being used in the work world. Anyway young people today who are used to carrying around their computer and making their phone calls from the same device, ie, cell phones, might be surprised to learn that laptops were not always as convenient as they are now. Despite their name, laptop, it was very uncomfortable to hold this new size computer on your lap. This is because the laptops generate Heating, and could even burn your thighs if you continue to use the laptop on your actual lap. Therefore it became necessary to figure out how to have cooling systems that would work for laptops. At first the answer was cooling platforms. Cooling platforms were simple devices that would hold your laptop computer up in the air about 6 or 8 in from your lap or from your desk or table. These cooling platforms sometimes had a built-in fan. If there was a fan built into your little cooling device, you would of course have to plug it in. That often meant that the freedom associated with a laptop computer was really not accurate. You could not carry your laptop anywhere you wanted to go. You had to have a place to plug in your Cooling platform. whoever invented the cooling platform really was quite smart, as he saw a need and he created something to address that need. Of course, many people today have forgotten all about the cooling platforms that you used to have to buy once you bought a laptop. Laptops have come a long way since then oh, and we no longer need secondary cooling to keep them from burning our thighs.
