We already covered Logitech's
The Logitech Illuminated Keyboard looks like the most interesting of the new bunch. A sharp design and an adjustable white LED backlight are the highlights, although it also uses Logitech's fantastic PerfectStroke key system, a carry-over from the high-end
We're less enthused by the diNovo Keyboard for Notebooks. Logitech bills it as a full-size, luxury accessory to free you from those cramped, overheated laptop keyboards.
We can certainly see why you might want to use a full-size keyboard when your laptop is parked on your desk (that's how we're typing this very blog post, in fact), but we don't see why you'd need a "for Notebooks" model to accomplish this task. At 17 inches long, it's not particularly portable, and at $100 it's no bargain, either. Perhaps if you like the styling of the diNovo Edge but you want a smaller, less expensive model this would make sense.
Finally, the Cordless Desktop S520 is a relatively straightforward, affordable cordless mouse and keyboard set. For $60 you get a standard 1,000 dpi laser mouse, and a round-edged keyboard with the usual array of hot keys and a funky-looking wrist rest.
