This is literally the job that Pat has wanted his whole life. He left Intel when PSO made it clear he wouldn't get it. And he showed them - named one of the top CEOs in the country at VMWare. If you see what is happening at VMware and Dell, you can see that there is now an opportunity for him to return that wouldn't have existed 2 years ago when there was a hope VMware would be a standalone company. Now VMware market cap is more than Dell, that owns most of VMware...so guess where that is heading.
Pat probably feels like he owes it to Andy to fix Intel...
