This is so people can see if something is going on inside the computer they don’t know about. The hard drive usage should be in both percent and mb/s read and write display on the desktop computer, and a laptop. Not on the actual screen, but on the laptop and desktop chassis. This is so people can see if something is going on. People should learn and have instructions on how to use CTRL ALT DEL to see and terminate processes that are using system resources. Computer fans should be quiet, fans that make a lot of noise are because of processes like “Windows update” working in the background, bad cooling, or a lot of processes or viruses working on the computer. They can make low light lamps that do not affect the user’s view on the screen, and the ability to turn them off so they do not disturb the user while watching movies. So many people do not understand when something is wrong with a computer! These meters when you do nothing should be close to idle 1-5 % maximum or the computer is too weak. Same with smartphones it should be able to bring up a “Task manager” like windows to get vital data about the smartphone/Tablet.
