IE8 improves customer service, and sells more products…
IE8 Web Accelerators and Web Slices add another mechanism for your customers to interact with you in the way they choose, from where they are.
This video describes how ASOS have achieved this:
They have made it easy for their customers to search for products from where they currently are, they can easily store their favourites and be notified of any changes, and finally they can use well understood and accessible search methods to locate products.
All of this provides a better service to customers, and sells more products for ASOS.
