nk497 writes "Dell's 'Project Sputnik' laptop is now on sale. The XPS 13 Developer Edition comes with Ubuntu 12.04 pre-installed, and costs $1,549 — $50 more than the same model running Windows. The Ubuntu Ultrabook is the result of a skunkworks project to optimise the open-source OS to run on Dell projects, to create better laptops for developers. The idea of the project was to create a laptop for developers, based around 'the idea that developers are the kings of IT and set the agenda for web companies, who in turn, set the agenda for the whole industry,' Dell said."
