I agree totally with this as I just can't imagine using a touch screen to play most games on, some simple games yes but complicated games that require moving and shooting/selecting weapons/reloading all done in very quick succession, I can't see it and personally can't see a time when I will need it unless future games are only playable by using this interface
Also what about the health issues when using a touch screen, in a work environment such as at a check out sitting close to a small screen with big icons which does not require any degree of accuracy might not be too stressful on the body but consider using a big monitor and your body posture.
Your monitor should be about arm's length away when you're sitting back in your chair. (Sitting too close or too far from your screen can cause eyestrain). If you have a large monitor - 20" or larger - you should sit slightly further back, so how can you comfortably touch the screen
If you are constantly leaning forward to touch the screen you are straining the lower back muscles and other parts of the body unnecessarily.
Touch screens have their place on smaller mobile screens, tablets. phones, etc but for big monitors used for prolonged lengths of time it seems pointless, no pun intended
