There was much hassle in the media about the part-time job of Andy at his new company. I think IBM has a bigger problem: It looks like they will totally loose an really important person :
Until recently, Papermaster was IBM's vice president of microprocessor development and had been at the company for 26 years.[...]
According to the complaint, Papermaster informed IBM that he'd accepted a senior executive position at Apple that involves working closely with CEO Steve Jobs, providing technical and strategic advice
Whereas Andy will still work for Sun on a part-time basis, this looks like a large area of scorched earth, as IBM and Papermaster are already in lawsuit mode about the new job at Apple. Papermaster is important for IBM, as he was the guy who oversaw the development of Power proccesor line and recently the development of IBMs blades.
