Yes and no, if you are a person who are by now very accustomed to touching the screen of your laptop, it comes as second nature when working with documents such as massive worksheets as it is just easier to point where you need and zoom in/out. And it works magically when you have a few people say working on financial model or doing an audit. So it all depends on what you use it for.
Maybe your local stores do differently, but for the past 2-3 years now pretty much every Windows laptop I see on display comes with touchscreen. I am not saying it is good or bad, but they put on everything big, small, clamshells, convertibles you name it
