Have you noticed that more and more laptops are shipping with touchscreen displays? Big-name manufacturers like Lenovo, HP, Acer, and Asus have all released their own touch-friendly devices. Some of these are what’s known as a “two-in-one laptop”. These can be used as a normal laptop. But they also have a hinge which allows the user to stow the keyboard and trackpad behind the display, in order to turn it into a tablet computer.
