Trackpads are the tool of the Devil. I just disable it and use a wireless mouse.I know what you mean. That's why I buy laptops so big that they could almost be mistaken for an all-in-one PC, lol. My current laptop has a numeric keypad on the right (like a standard keyboard), and 95% of the time I use it on a table with a mouse, instead of using the trackpad which I hate.
And yes, I often accidentally close tabs/windows while typing, because the heel of my hand rested too close to the CTRL key. This causes me to scream.
