If there is valid criticism of Ottellini its because he didn't have Intel make chips that competed directly against ARM much sooner. Ottellini originates from sales. He probably saw Intel's challenges in mobile as a sales problem, not a product design issue, which of course it was. Who ever fills that role going forward needs to have had direct revenue generation responsibility and at one time led product development, manufacturing and/or sales. CFO's can be talented people and they may be adept at schmoozing analysts but they rarely contribute the kind of innovation Intel needs to prosper.
The best candidate for the role isn't presently at Intel and doesn't need the job.
