Conduct an experiment to compare m-commerce at Wal-Mart and Target. Start the stopwatch, load Wal-Mart’s site, and search for a Fodor’s travel guide to Mexico. Add the product to your cart, check out up to the point at which you would enter a credit card number, and then write down the time from the stopwatch. Do the same experiment at Target’s site. How did your time estimates compare for the two m-commerce experiences? Overall, which site do you think offers the best user experience?
