I LOVED the mobile emitter. It allowed the Doctor to grow. If you watch Season 1-2 EMH and then watch, say Season 5 or 6 EMH...totally different. Still sarcastic and clever, but the bitterness is gone and him exploring his new life and gaining new experiences is what made his character arc so awesome.
I don't exactly agree with the last part of this statement. The sentiments that he fully and unambiguously expressed in Author Author, suggest that even at the end, he retained a keen appreciation of the limitations of holographic enfranchisement in Voyager's society, and to satisfy the greater reach that the episode aimed for, contemporary life in the Federation. Certainly, the degree to which Doc's persona and the perception of his ability to contribute to the ship's welfare beyond those four (or more) walls were given any credence, grew by leaps and bounds, but his recognition of his Otherness was still there, illustrated by any number of comments by him throughout the series run.
To have become one of the main axes of the show as I suppose became pretty clear early on needed to happen, we were going to have to see the introduction of the mobile emitter, as the homegrown solution wasn't going to cut it, even forgetting about the haha gaffe in Persistence of Vision. Besides, how on earth could an ECH possess any kind of gravitas if he was stuck performing those executive functions from sickbay!!!

By the way, kudos on your star turn, Cap'n!
