I know I might be in the minority here, but I don't love the feel of the old one. Mine was wireless and the numberpad and overall shape were huge. the whole point of wireless is clean and mobile so for me the updated keyboards in the wireless flavor are a godsend. Also, I agree totally with the production point raised by samh004, I am a big believer in modular application of hardware components (or at least semi-modular for production purposes).
