Samsung has just taken the wraps off of its highly anticipated Galaxy S III and, in a move similar to Nokia's efforts with the Lumia line, decided to package extra services and features to further differentiate itself from the competition. Mentioned onstage were the S Health "personal wellness app" and an enhanced Music Hub cloud service with access to over 17 million tracks and an iTunes Match-sounding "Scan and Match" feature. Music Hub will launch in seven countries, while the matching feature is supported in six of those. There's also a hub for Games that promises quick tie ins to social gaming and a Video Hub with TV and movies. One other new feature is support for MirrorLink enabled headunits that should bring access to all of these things even while you're driving your car. Finally, there's NFC-based mobile payment support that should get some use among visitors to the Olympic games this summer.
