Many people when they go shopping for a computer look for a model that contains the essential features. There are others, however, who are interested in the little extras. They want to have a model which contains many fancy features; add-ons which are good to look at, but which serve very little purpose. These rather attractive but inessential features that you buy along with a gadget are called “bells and whistles”.
*You don’t need the bells and whistles. They will double the cost. *Ramesh likes to buy gadgets with all the bells and whistles.
