Dell on Tuesday reported results that it touted as producing records but which signaled continued problems in its mainstay home PC business. Although its revenue was up two percent from winter a year ago to just over $16 billion, its profit was down 18 percent to $764 million. The largest drag was in the consumer group, where its revenue dipped two percent to $3.2 billion and it saw an extremely sharp 43 percent drop in operating income to $39 million.
