The action of a real piano can daunt a lot of people who practice on "easy to press" digitals. It is nothing that cannot be solved by playing on real pianos for a few months. It won't require a total reassessment of your entire playing ability. I have however found that digitals do not emulate the effect of the sustain pedal very well. Because they can only simultaneously play a limited number of sounds many notes can vanish if the sustain pedal holds many notes. This is detrimental to your piano development, much more so than the action to press down notes in my opinion.
An acoustic piano in my opinion sounds MUCH, MUCH better than the most expensive digital piano at the same price.
