Selfishly I'm very interested in following a private Dell,as tech tends to lead to huge companies in monopoly/winner take all verticals. Dell being private is a decent case study to see how well a private company does against its public counterparts, specifically wrt short vs long term investment.
If you were wondering how the new company is doing post merger...
Moody's just upgraded Dell's credit rating from Ba2 to Ba1 following the merger. They claim that even though the new entity has significant amounts of debt and leverage, its overall credit profile has been upgraded.
The tracking stock, DVMT, that EMC owners were given has traded pretty well since it was released, it's slightly up, so atleast people who want out of the new entity have an easy avenue.
