Yesterday’s announcement that Best Buy will carry the MSI Wind was a big one. It means that the American electronics retailer will be expanding its netbook offerings in its brick and mortar stores and on its Web site. When we spoke with Best Buy, they stressed that it would be expanding its netbook selection and also making a concerted effort to inform buyers about the differences between a netbook and a notebook. Best Buy seems to be starting that effort today on its Web site. The retailer put up a netbooks category within its computers section and has put up its own definition of what a netbook is. Highlighting that a netbook is not a replacement for a main PC, Best Buy defines netbooks as a “mobile device designed for the Internet.” We appreciate that the retailer is making an effort to tell users what netbooks can and can’t do. We have been doing that for a few months, but its nice to see others in the industry educating buyers about the new product category.
