I use a laptop, a decent one, and you should know that most laptops comes with a trackpad, which I hate, and the way that I use it is a bit strange. Basically, I use all my fingers except my pinky, what makes it hurt is because I put all my fingers on the keyboard without my pinky touching any of the keys, occasionally it does, it'd just be hovering over the keys and I use this way of typing ever since Feb. so it's pretty bad, after I finish one texture, I can't move on to the next texture right away because I just can't with my pinky in ache.
