Australian telecommunications company Optus is dumping 5,000 Macs as part of a multi-million dollar overhaul of its information technology architecture. Australian IT reports that the move ends “11 years of loyalty which began in 1992 with the rollout of the user-friendly machines across the company in the world’s largest business deployment of the computers… Optus was now in the process of moving all its users to Windows-based machines, insiders said. In recent years, the Windows machines have started to push aside Apple in Optus, grabbing about 50 percent of its 10,000 desktops.”
