Is the notebook touch screen practical?

Personally, I don't think this is practical. It's better to buy a tablet computer. And if you click on the touch screen frequently, it will actually do great harm to the screen. Moreover, many softwares still need mouse operation, and the operating range of stylus is limited, so it is not very practical in general. At present, there are fewer computers with touch screens on the market, and the sales volume is not much, which should be the reason.
