Okay, something new. I hate have to put batteries into my wireless devices and her is a device that takes the ambient light around your office setup and uses it to keep your keyboard up and running. Though I am a little late in reporting this… I think that this is a great concept to get one more worry off of my already so full table.To have a keyboard that is wireless and also have no worry  for having to provide it power seems like a God-Send. Thanks Logitetch. Now show me how you are going to do this with a mouse, too!
