NEW YORK ( TheStreet) -- With computer giants Hewlett-Packard ( HPQ) and Dell ( DELL) marred in a neck-and-neck race to see which one can spiral more quickly into irrelevance, I'm starting to wonder what metric will be the first to reach to zero, market share or market cap?As harsh as that may sound, both companies have taken different paths towards futility while yielding broadly the same results. However, none of their attempts to avert death to this point have worked. Dell has tried to buy its way out of trouble, while HP has tried unsuccessfully to transform itself into Apple ( AAPL). Worse, it seems the biggest mistake both companies have made was thinking they can compete in mobile instead of maintaining their focus of turning into the mold of IBM ( IBM). It's hard to imagine if another company deserves more credit for having anticipated correctly the demise of the PC industry. IBM was smarter than many critics care to admit. However, for HP and Dell, it's not too late to shed the woeful hardware business and transform themselves into a complete enterprise services company. After all, IBM proved that it can be done. The company's most recent earnings report prove what is possible when great vision and sound execution comes together.
