King size beds and pillow sizes...

I've been thinking about this ever since we decided to get a new (king-size) bed for our bedroom...

Standard Vs King size pillows on a king size bed...

While reading through domino I came across a bedroom bedding section and under "Beyond Standard Pillows" here is what it says:

"If you have a king-size bed, be sure to use king-size pillows to fill the bed's whole width."

What are your thoughts on this?
