Evaluate the usability of two Web sites that sell large-screen LCD high-definition televisions. A list of links to companies that sell this type of product is included in the Online Companion for this exercise, but you may use other sites if you wish. In your evaluation, compare the sites on how easy it is to learn about the product and purchase the product. Your report should include a section of about 200 words in which you describe the criteria you used in your evaluation, a section of about 300 words that summarizes your findings, and a section of about 100 words in which you present your conclusion.
