I've been using corded keyboards for years and like most people I get tired of the wires, wires always clutter your desk and they really limit what you can do or where you can have a keyboard at.
So when I went out to purchase a wireless keyboard I stumbled on the logitech LX 710 Laser keyboard.
The keys on this keyboard have a very rapid response on them which is great because I can write very fast using this keyboard. There is also no delay like with most wireless keyboards.
The other thing I love about this keyboard are it's quick media buttons which make opening media player a snap. I really haven't tried this keyboard on a lot of video games but it seemed to work great on doom 3 which is a very responsive game.
The mouse is about the size of a Apple Mighty mouse, it is really a snappy mouse I even had to turn the response time down to use it.
Overall this is a great little keyboard and mouse set for someone who want's to be free from wires forever, this would be a great option if you are limited on desk space.
