Dell offers hardware and basic software support, including installation, network connectivity and configuration. Additional upgrade services and support can be purchased directly from Canonical, Ubuntu's corporate steward.
Dell started shipping its first Linux-based consumer PCs and notebooks in the US last May. Company executives declined to give out sales numbers for the systems, but pointed out that they wouldn't have expanded the consumer Linux programme if they weren't satisfied.
The computer maker had predicted that it would expand the offering internationally soon after the US launch. On Dell's IdeaStorm customer feedback website, an item requesting Ubuntu PCs worldwide has attracted more than 41,000 supporters.
