I agree with justtrading's post above 1,000%. I have a mouse pad just like that, very old, been around the world, and has caused many linty mouse balls. Dear to my heart the thing is. ;-)
I am buying only ASUS parts and have never ever regret about that really. I am not sure about Intel, MSI, Gigabyte, Asrock, Acer or some other more smaller manufacturers of them so it's all fine and dandy here anyway. Take a closer look to it next time.
