Tila Tequila

Would it be a good idea to make a computer that could taste?

We already have seeing features of computers (like cameras and web cams), and hearing features of computers (like voice recorders or video chat) so what about a computer that could taste or enable you to taste different things. Like food samples. There could be a pad or something on the computer that you could lick to taste a sample of food before you buy it or you could put a sample of food on the computer tab and it could taste the food to tell you if it is worth eating or not or maybe identify the ingredients. Could this be possible to do? What do you think of this idea?
