Touchscreens on a laptop is still quite a controversial subject. On one hand, people think it's a no-brainer, and that every display should have some kind of touch functionality. On the other, people think touchscreens are only welcome on phones or tablets, and that laptops and other screens should remain non-touch.
There are different pros and cons to having a touchscreen of course. One of those pros is easy manipulation of whatever is on screen. Even on a laptop, sometimes it's nice to be able to just tap on an icon or swipe up on a webpage to scroll. A con would be touchscreens leave gross greasy fingerprint marks on your expensive laptop screen.
