I do have external Apple touchpad but dropping it in front of the keyboard sucks hard. It is on lower level than keyboard and ergonomy is much worse than using it with Macbook laptop (I mostly use it for two/three finger swiping). Ideal touchpad would be non-flat and nicely integrated with the curve of ergo keyboard (I know, sounds difficult with split keyboard).
