It's not a problem, It's a light sensor for the auto-brightness setting.

That's why on some cases there is a hole on the top.
 
speaking of... i have turned on and off the auto-brightness and i notice no difference :confused:

It depends on where you are. If it's at night and you're in a dark room it is definitely noticeable, the screen will be apparently dimmer than usual. If auto brightness is enabled for you and it doesn't change for your surroundings, then your iPod may have a hardware problem.
