I hear it all the time when it comes to web design "we'll make the site and then the designers can make it look pretty." Good design is more than just making things look pretty. Good design is creating websites, and products, made for human beings.
Sure looking good is a part of appealing to people, but it goes way beyond that. The iPod is more than just pretty, it was designed to work well. The scroll wheel of the original and the touch pad interface of the iPhone are examples of great design in action.
Do you have great designers working for you?
