Any support supporting the Web will also support the WebBook. One of the ways a computer product thrives in the marketplace is with third party support. The WebBook is optimized to surf the Web. The WebBook is not a computer. It is computer based and it does things that other people need computers to do, but it is more of an appliance.
People already have other kinds of computers.
Students use home, dorm or classroom computers. Employees of corporations use the desktops at work, and connect to company mainframes or home computers which must run software compatible with their office applications. And where to order the stuff from. The WebBook is for connecting people with ideas. It's a Model T for the information highway.
