The Eclipse II we saw at E3 from Saitek is finally shipping. The keyboard features a backlight, similar to the ones people love on the MacBook Pro laptops, but in three different colors: purple, red and blue. There's a dimmer switch on the keyboard to switch colors and adjust the intensity.
In addition to the lighting, the 'board comes with four large rubber feet so it doesn't go sliding, and an integrated wrist-rest for carpal-tunnel prevention. Available now for $70. It should hold you over until the Microsoft Ultimate Keyboard is released.
