Working out company culture
If Dell and EMC can get together on the culture thing, they may have a shot. I've heard way too many horror stories about recently bought companies with managers that can no longer make their own decisions and instead have to go through an office located in another city for simple decisions better delegated to local offices like vacation requests, office supply procurement, and so on. When a manager can't manage, the people under them get disgruntled and either their productivity goes down or they jump ship for saner waters. If they can get past the madness reorganizing and putting new roles in place, maybe they will be come a force to be reckoned with.
