RHaseltine: I know thats the teory but I often find myself touching the pad by misstake as one do not want to lift the pen more than what's absolutely needed. So I find myself doing misstakes now and then with the pen and as I never do the same misstakes with the mouse and as it's so easy to use both at the same time there is no reason to use the pen for windows operations. I also find find the pen putting more strain on my arm and hand than the mouse do.
