We as an organisation like to take our time. We wouldn't welcome a new joiner with a PC on his desk. Much more fun to see him struggling for weeks with our internal IT approval processes. We happily pay millions to Microsoft to get the privilege of using Windows Xp / 32 bit systems a little bit longer (I have now almost more RAM in my mobile phone than my workstation). In fact I suspect many of the critical infrastructures of the organisation are running on COBOL. We'd probably still use CRT screens if our IT department could source them. We are certainly still using blackberries (I hope they will stash enough devices before RIM goes bust).
