Mark Shuttleworth has announced that Dell will expand its Linux offerings. “What’s been announced to date is not the full extent of what we will see over the next couple of weeks and months,” Shuttleworth said an interview late on Wednesday. “There are additional offerings in the pipeline,” he said. Shuttleworth founded Canonical to provide support for Ubuntu Linux. A Dell spokeswoman, Anne Camden, declined comment, saying the company does not discuss products in the pipeline.
