Handful of Concepts - Computer Coffee.

"A computer which serves you coffee and biscuits"

As cliché as this idea is because everyone has thought of it, I still feel it would be a good great idea. The computer will know when your feeling grouchy or tired, and just like a coffee machine, a cup will drop from behind the computer - filling your cup to the rim with warm, rich coffee. Then as a compliment to go with the beverage - it will serve up 2 of your most favourite tasting biscuits.
