Agree, I often end up brushing the touch pad accidentally with the heel of my hand while typing, and inadvertently moving the cursor somewhere up the page. Maybe someone else can weigh in on any advantages to having such a large touch pad.
You can drag further with it or use it at a higher sensitivity and drag as much as you used to. There are also more places you can start dragging so it’s more likely you will naturally touch your finger down and start dragging.
