What is the diff. between a netbook, notebook & laptop?

A Notebook and Laptop are the same thing. People were suing computer companies saying they were getting their laps burned and since the company called it a laptop, they were selling unsafe products. So they use the term Notebook now. A netbook is a computer that is usually smaller than 13" and is mostly used to access the internet. Since they are made to go on the internet, the hardware specs are usually low to keep the cost low.
