Definatley not a fan of the kenisis style... that keyboard looks like someone took a cutting board, dumped some keys on it, and whereever they landed, they stayed...
I dont know what kind of switched they used, but the original Microsoft Natural Keyboard i liked the feel and sound off.. and the one im using currently (tho its white, and can use my once every 2 month, pop the key off and clean it routine)..
I did some searchingin the the forums and i came across a topic where someone bought the northgate evolution.. interesting, but if i was gonna drop coin like that i would bite the bullet on an ortek mck, or an avant stellar.. both of which you can use to put a dent in the fender of a 77 cadillac..
Im leaning twords one of these choices, even tho there not ergos:
Logitech DeNovo (the new one with the glidepad)
One of the Razer gaming keyboards:

I see OCZ makes keyboard now:
