My mother who bought me my MBP back in 2009 fears that if I were to play games on it, I could damage the keys of the keyboard during gameplay. Solution? I hook up a USB keyboard to prevent damage but this computer is a notebook, designed for work and play on-the-go. Do I necessarily have to carry a USB keyboard with me 24/7? Even during non-gaming activities the keys could get damaged. What are the chances of the keys stop working due to such activities?
