When Ubuntu Linux was still in early development back in August 2004, Canonical founder Mark Shuttleworth filed a tongue-in-cheek first bug: that Microsoft had a majority of PC market share. Little did he realize that he'd have an excuse to cross that bug off the list in 2013. Since computing now includes phones and tablets, he argues, that leaves the traditional PC (and therefore Windows) in the minority versus Android, iOS and other platforms. Whether or not you agree with that market interpretation, Shuttleworth is ready to move on -- he feels it's better to polish Canonical's own cloud, desktop and mobile efforts than to target someone else. It's undoubtedly easy for Shuttleworth to make peace when the battle is supposed to be over, but we can't object to such a healthy attitude.
