As Dell buys Exanet's assets, CEO Mark Weiner must be feeling vindicated a bit, I imagine.  The company flamed out after some of his board block an earlier Dell deal.  Some history here.  Also former CEOs Rami Schwartz and Arnon Gat, both of whom led the company within the past three years, must be feeling something too. 

As a search professional, it may be heresy for me to say so, but sometimes a new CEO is not the answer.  Too often boards look at replacing the CEO as a magic easy button that will make their problems go away.  New CEOs can fall into the same trap.  (nobody gets to be a CEO without some ego.) 

Don't get me wrong, new CEO's may bring new solutions with them, but they still have to be solutions the same problems the previous CEo faced.
