Cordless MediaBoard
The Logitech Cordless MediaBoard is the first Sony-certified keyboard released for the Playstation 3. The keyboard features a built in trackpad to offer easier navigation without the addition of a cordless mouse. The MediaBoard uses a USB dongle and a 2.4GHz RF connection that gets you a wireless range of 30 feet, according to CNet.com. Also according to CNet, there are no PS3-specific buttons, which are needed for seamlessly navigating the menus and Internet. One advantage is that this keyboard can also be used on PCs and Macs.
Cordless MediaBoard Pro
The Logitech Cordless MediaBoard Pro is the successor of the Cordless MediaBoard. The main differences are that this keyboard features PS3-specific buttons, which the MediaBoard was lacking, and it uses Bluetooth instead of an RF connection. This advanced model also features media playback keys to make watching movies on your PS3 easier. Instead of the gray and black look of the original MediaBoard, the Pro model has adopted a piano-black finish to match that of the Playstation 3. According to Legitreviews.com, the keyboard is easy to install as you simply put batteries in it and turn on the keyboard's "discovery mode" so the PS3 can find it.
DiNovo Edge
The Logitech DiNovo Edge is one of Logitech's high-end offerings. Originally made for the PC, this keyboard also works well on the PS3. This wireless Bluetooth set features a trackpad so you won't need an additional mouse with this model either. According to CNet.com, this is the first rechargeable wireless keyboard, which means you won't need to keep wasting money on batteries. CNet also claims that the trackpad on this model isn't very responsive. This offering also features media-specific buttons such as play/pause, rewind and fast forward.
DiNovo Mini
At six inches long and less than one inch in height, this is not what you would probably want to use as your main keyboard. That said, the DiNovo Mini by Logitech is great for use with a PS3 unless you plan on doing a lot of typing. The keyboard features a clam-shell design to close it and make it look more aesthetically pleasing. This mini Bluetooth-capable keyboard features a trackpad that also functions as a D-pad for navigating linear menus. If you want a small offering instead of a full-sized keyboard taking up space, the DiNovo Mini is a good PS3-compatible choice.
