Somewhat related to my previous post, I've always been interested in the Optimus Keyboards, even if the $1564 price tag is way too steep for me. It looks like they have to make these by hand right now, though. Maybe if things pick up, they will be able to start mass-producing them by machine and the price will go drastically down. I would think $200-$300 would be the right price point for me, depending on the tactile quality and durability of the keyboard.
As a much cheaper alternative, this Slashdot comment points out the Deck Backlit Keyboards. The backlight wouldn't do me much good, though, as I rarely look at my keyboard as I'm typing.
For the record, I'm using a Logitech cordless keyboard that I've had for a few years now.
