I have both and can say the Eclipse II is the better keyboard. While the 2nd one gives you a choise of three backlit colours, I stick with the blue. You get media control keys on the 2 where you only get volume on 1. The back light is fairly dim on both, but are ok in low lighting conditions. They both have a nice soft touch keys and are quiet to use. I simply prefer the look of the 2 over 1.
