This keyboard seems to be a huge jump forward in the ability to drive your computer aound while being able to minimize the risk of repetative stress injury. I like the lap adapter for it — I’m having problems at work where I’m using an ergonomic keyboard that’s resting too high on a table top.
I’d love to jump in and give one a try; however, the tarrif’s pretty steep: $675.
As a psuedo-side note, a good keyboard is only part of an ergonomically sound workplace. You need a good chair (I dropped the big $$ for Aeron chairs), good monitors (note the plural), and a keyboard tray which lets you get your keyboard at the perfect height. I’ve got one from Humanscale at home and it’s a joy: rock solid and extremely adjustable.
