One of the features I specifically look for in a laptop is "NO TOUCH SCREEN". I really don't understand it. Why would I want touch on a laptop or desktop PC?
The reason we could never reproduce the crash before was that, being techies, none of us had any modern laptop, personal or not, with a touch screen. The client, being less technical, had some of their workers with touch screen laptops and the then-recent touch-focused version of Windows (which we also tended to avoid).
But I'm a "don't leave smudge marks on my screen" type of person.
