				NooK Color help needed
			 
			 
			
		
		
		To go on-line do I need a wi-fi card?  Is buying one like signing up for a monthly charge or only when you actually go on line?  I don't have a clue.  She wants me to make sure I want it before I open it, because if I open it I can't return it to Barnes and Noble.  Is there anything on the Nook allready, like games or anything else that is useful?
