I've also gotten very use to the media and additional silver buttons along the top of the MS Natural 4000, which I've set as short-cuts for various things.
I almost need a separate little keypad that I can program before I give up the 4000.
Knight Plus comes with the detachable(you can move it to left or right) numpad. And X Bows keyboards support QMK[1]. So you can map any key to any other key or macros and add layout on top of it.
