I was in our University Bookstore the other day looking at software when I overheard a salesman talking to a lady about an iMac.

Salesman: “It has a built in color monitor and comes with a mouse and keyboard–”

Customer: “Does this thing come with a battery backup system?”

Salesman: “No, but we have one over there for $99.00. Do you have problems with power outages?”

Customer: “No, but I don’t want to lose all of my Microsoft documents everytime I turn off the computer!”

Salesman: “You don’t need a battery backup for that. That’s why it has a 4 gigabyte hard drive.”

Customer: “A hard what?”

Salesman: “A hard drive. It’s like a whole bunch of floppy disks inside your computer that you can store documents on.”

Customer: “I want the battery backup.”

Salesman: “You don’t need it.”

Customer: “Why?”
