The mouse that comes with the diNovo Cordless Desktop is actually Logitech's "Cordless Desktop Optical Mouse for NoteBooks". This mouse retails for $39.99 and it is "mobility without compromise" according to Logitech. It features a basic optical sensor, two main buttons, a clickable scroll wheel, and RF connectivity. Like the rest of the Desktop's input devices, the mice is powered with two AA batteries and should last for at least six months on a pair.
Though it is not too much too look at this mouse is of the better notebook mouse out there. It is a nice size, has a good feel too it, despite its sub-normal size, it comes with a nice neoprene carrying case, and connects to a small USB dongle, not a big stand. Despite these features it has a number of obvious faults, the most damning being its lacks extra buttons (forward, back, etc), and its lack of a high-end optical engine. These features are not something you would normally expect on a notebook mouse, but are consumers really planning on using this as a notebook mouse?
I am sure some users are going to buy the diNovo kit and use it as a desktop kit and the take it on the road with them, just like Logitech envisioned. In an ideal world this would not only add to your productivity but it would help justify the costs of this package. But, in actuality, it seems more likely that people are going to buy the diNovo kit and leave it at home or in the office. No only want to be left without a keyboard or mouse at their main computer, even if this is just for the time from when they pack to when they leave. I guess this would be a good security measure though...
