We can be honest with each other and say that many of the wireless products on the market aren't that great, especially for gaming. I have tried to use a normal wireless mouse and keyboard to play games like COD and others before and ended up with ghosting that was bad enough I expected to see Casper pop up on screen. There are some wireless rodents on the market for gamers, but most of the wireless gear is still aimed at the general computer user.
Logitech has debuted a nice looking new wireless desktop for the general computer user called the Logitech Wireless Combo MK520. The wireless desktop includes a full-size wireless mouse and keyboard. That keyboard has all the one-touch media controls that you need to control your content and a full number pad as well.
The keyboard has keys that use the Logitech Incurve design to make it easier for your fingers to glide from one key to the other, making typing easier n adore comfortable. The full-size mouse is an ambidextrous design with a scroll wheel and soft rubber grips on the side. Logitech is mum on sensitivity, but you can expect in the 800 dpi range. The mouse uses a laser promising accurate tracking on anything other than glass or a mirror. Official pricing is unknown and the MK520 should ship soon and it uses the Logitech unifying receiver for connectivity..
