Dell's Domination Ending?

Dell has reportedly missed two consecutive quarters with regards to expected sales. They believe that its finally time for the dominating PC distributor to rejoin the other firms on planet earth. I think they don't have anything to worry about. If you were to look at other firms' sales i'm sure they'd probably be experiencing the same results. The article did mention some problems with their processes and quality which can cause some huge problems for the company. Maybe they should look into improving the things that they can, it can only give them a more competitive advantage.
