If it's a convertible it has its uses I guess considering you can turn it into essentially a big tablet, although I don't like the keyboard being exposed on the bottom..
If it's an ordinary laptop I really don't see the point; among other issues it just feels awful to try and make more or less precise inputs when the screen hinge is actively fighting you by moving the screen back with every touch.
Then there are the smudges. I watch a lot of videos and stuff on my laptop and just can't stand when the screen is all gunged up, it's disgusting.
