White Glove is a marketing effort that Samsung has been using to convert Apple-using celebrities and influencers and get them to start using Samsung devices. The company will often send someone over to a celebrity, sit down with him/her and talk them through how the device works, and then leave the device with them as a free gift. In the case of Dana Brunetti, this resulted in him keeping both the Galaxy S III and the iPhone with him for a month of use, after which he put down the latter and started sticking with his S III, a device he says has many useful features that make his work easier, including widgets.
It's a pretty interesting program that Samsung has going, and the source article goes into detail of what makes it tick, letting the Korean manufacturer take away at least some high-profile celebrities away from the iPhone, so go ahead and give it a read.
