Ubuntu is a version of Linux, the open-source OS that is chipping away at Microsoft's domination of the software market.

Chipping delicately, it has to be said. According to market analyst IDC, Microsoft's various Windows versions have more than 95 per cent of the market for desktop and laptop PCs, followed by a resurgent Mac OS with about 2.5 per cent, then Linux, which also has many flavours, with about 1 per cent.
