I read a review where a customer bought the WKB-120 to replace a Microsoft Natural style keyboard. The thing is that the WKB-120 is not contoured or split, so for anyone used to an ergonomic keyboard, it will not feel "right". If any customers want to try to "natural" style with a pointing device, try the Adesso Tru-Form with touchpad that is PCK-308T and it comes in black too. That has a similar feel with the added touchpad convenience.
