Funny and yet alluring keyboard design, but if it were me i'd have the number pad on the other side, i like to keep my mouse hand and my typing hand as far apart as possible ;-). One idea is to remove the f-keys and map them to numpad together with additional fn key. Either way there are far too many keys, mapping more fn keys will reduce the key count quit abit. Either way that keyboard will take ages to unremember all the stuff you learn with your original keyboard
