The diNovo Edge is actually the third keyboard in the diNovo line. After the first one got so much attention Logitech decided to make some tweaks to it and address a few of the problems, like the poorly chosen mouse, and released a follow-up product. The diNovo Media Desktop Laser changed the color and bumped up the price by $50, but also upgraded to a MX Laser mouse and Bluetooth connectivity. The Edge is the first diNovo keyboard to be part of Logitech's Advanced Peripherals line. These are high-end components whose goal is to match style with serious performance. This by itself does not tell us much about the keyboard, but we know that is has been promoted to the same category of items as Logitech's acclaimed Z-10 speakers and MX Revolution mouse.

SteelSteries is basically filling in their SteelSound lineup. They started with the high-end 5H ($99.95) and the 5H USB ($119.95) and now added the 3H ($49.95) and the 4H ($69.95). This rounds out their audio offerings and gives consumers some less expensive price points to work with.
