The cosmonaut's crusade for free computers
What would you do if you'd made £400m in the last tech boom? Relax and take it easy?
Well, for Mark Shuttleworth, the choice was easy, writes Ben King. After a quick trip to space as an amateur cosmonaut, he went back into computing.
But his choice of projects has been a fascinating one. He launched his own desktop operating system. So instead of a Windows computer or a Mac, you can run your machine on Ubuntu.
Even with those deep pockets, taking on tech industry titans like Microsoft and Apple will be tough. But Shuttleworth is giving his product away for free.
