Dell on Tuesday epitomized the tough conditions for Windows PC builders with flat results and a poor outlook. Its overall revenue, as well as its home and large business PC revenues, were up just one percent over a year earlier. While its net income was up 60 percent to just over $1 billion, the company warned that its summer performance would be flat and lowered its growth expectations for the whole year, down from five to nine percent to just one to five percent.
