The more photos of the CP4 I see, the more I like how it combines all of the physical design elements of the CP1/CP5 and CP300/CP33 that I like: body of the CP33, buttons of the CP1/CP5, sliders of the CP300, silver/Rhodes-esque stripe on the CP1/CP5, same wheels as the CP1/CP5, etc. It's an attractive broad board.
