Touch screen on a laptop like this is like an air conditioner on a bike.
It might be a 'cool' marketing gimmick, but it certainly isn't very practical.
Really? I found it quite natural to reach up and hit the screen often. I dont own one right now but I've used them a good amount. Is it necessary? Goodness no. Can it be useful for certain people? Yeah but I dont think everyone will use it like I do
