Interesting news, I've spoken to the man a couple of times myself. Sean Pelletier has left his position as Senior Technical Marketing Manager for Windows, Windows RT, and Apple notebooks at NVIDIA to take up a position at AMD. It's unknown what Pelletier's focus will be at his new job. 

Today BSN got word of yet another one of AMD's acquisitions of top-notch talent. We earlier reported on the acquisitions of people like Jim Keller, Raja Koduri and Roy Taylor among many others. Today, we got word from both internal an external sources that Sean Pelletier (Pelly), Nvidia's Senior Technical Marketing Manager for Windows, Windows RT, and Apple Notebooks. He has worked at Nvidia for almost 6 years and has primarily held a role in notebook marketing for quite a while. While we don't quite know his role within the company, it is known that he would likely help the company to head up their initiatives in trying to position themselves in the new middle of the notebook market.

Since AMD has recently launched their Radeon HD 8970 for notebooks, it remains to be seen what new products he will be responsible for handling.
