The pads need to be pressed to a steady force to keep them at the right feel for drums, but for synth and piano a lighter touch is suffice

but then most MIDI controllers do not even have that, and certainly not the level of the Kawai action which is truly a remarkable feel, you have to play it to feel it

Light as a feather - 3.4 Kgs only, I can play it on my lap, carry it anywhere, use any ready made headphone, use the bevy of adapters when I really need it for sound output, very good key feel, solid number of controllers and pads, can be used for automation with software and comes with a solid selection of free software including Reason limited, plugins from Garageband and the editor software for every parameter that can be saved in "scenes" which are essentially program parameter settings snapshots
