The Microsoft Student Partner is a way for students to affiliate themselves with Microsoft getting the opportunity to represent the company at their university and pick up some cool prizes along the way. Plus it looks great on your CV.
From the MSP site:
"Microsoft Student Partners carry out tasks such as organising guest Microsoft lectures, delivering technical sessions to their peers, conducting student events and giveaways on campus, and a whole lot more to help us deliver more value to universities and build better relationships with lecturers and students alike."
