I grew up playing the piano, then went on hiatus for two or three years, then took a year of harpsichord lessons (harpsichords have significantly lighter action. And narrower keys.) Now playing a piano is downright painful--I'm no longer used to the finger and wrist strength required to get a key down, nor am I used to the stretching required to hit larger intervals. The plural of anecdote is not "data", but I, for one, will no longer understate the difficulty in transitioning to a new type of action.
