The Logitech diNovo Edge Bluetooth keyboard is likely the most aesthetically stunning keyboard ever made for Macs, according to a review by Charles W. Moore [AppleLinks].
Charles writes a comprehensive review of the keyboard in which he pretty much agrees with Logitech's claim that this keyboard is the world's most advanced.
Logitech boasts that the diNovo Edge is the "world's most advanced keyboard," and after using it I have to agree that they may have an arguable point.
My second observation is that I've tested quite a number of keyboards over the past several years, and they have all had their virtues, but after I had put them through their paces I was always eager to get back to what has been my favorite keyboard by a wide margin for some time - the Kensington SlimType. Not with this one though. I find the diNovo Edge such a pleasure to use that I'm in no hurry at all to switch back. The SlimType is still probably my favorite keyboard all round, but this Logitech diNovo Edge is definitely a powerful contender, and of course it wins the appearance laurels hands-down.
