Personally, if I were Microsoft, I'd kill for the opportunity to limit foreign startup talent hires to a five year perked timetable. Over time, yes, engineers are engineers, and those perking will be a continuous opportunity for startups to hire. However, it doesn't help at all if you want to hire the world's top talent in {insert new technology that didn't exist 2 years ago}. And isn't that ideally what this is about?
