Additional control scheme is implemented, artworks are closer to the original. Character artworks look much better than the ones in TSoMI: SE in my opinion.
Also - The Secret of Monkey Island SE will be released on Mac (via Aspyr's download agent) and PSN and the Windoes version will be released on Telltale's online store (so far this version was only available via Steam):

"To recap: SOMI Special Edition coming soon to PSN and Mac, amongst other cool things. Tons of Playstation Home avatar stuff coming for Monkey Fans. Special Edition 2 hits this summer for XBLA, PSN, PC, Mac, and iPhone. Phew. And yeah - we fixed his hair." 
Facebook announcement seems to contradict LucasArts' official press release regarding release of MI 2 on Mac, but anyway:
Monkey Island 1+2 are not only among the best and most popular point&click adventure games ever made, together they are also my all-time most favourite game. I'm glad that they are remade in a such a cool way and that they can be enjoyed 20/19 years after their original releases by even more people.
