Dell has been quite successful recently selling a line of computers preinstalled with GNU/Linux. So much so that the company posted a blog on March 10 extolling the fact that Precision 5510, 3510, 7510 and 7710 mobile workstations are all available worldwide with Ubuntu preinstalled. What’s more, the company doesn’t hide Linux availability in the fine print or make potential customers find a special page to order from, which had once been its practice. Just go to the page for Precision laptops, find the one you want and tic the Ubuntu Linux option in the Operating System box in the Build My Dell section.
