This is one of Logitech's best items. As such it is one of the most expensive keyboards they make. With this Logitech dinovo edge model you're really getting an all-in-one package kind of deal. On the lower right-hand corner is a little pad that allows this keyboard to function as a mouse. This immediately brings to my attention perfect use for a home theater PC computer. A lot of people these days have a PC computer hooked up to a television monitor in with this computer they have a devoted system for media. Typically, people like to watch their media in the comfort of their beds or on the couch. This requires one to ideally purchase a wireless keyboard and mouse so that they can navigate while sitting far away from the monitor. The Logitech dinovo edge is absolutely perfect for this purpose since it has a wireless keyboard and mouse built into one.
