Enterprises addicted to Microsoft's nine-year-old Internet Explorer 6 (IE6) browser are having a tough time migrating to Windows 7, an analyst said today.

...

Organizations running IE6 have told Gartner that 40% of their custom-built browser-dependent applications won't run on IE8, the version packaged with Windows 7. Thus many companies face a tough decision: Either spend time and money to upgrade those applications so that they work in newer browsers, or stick with Windows XP.

But Windows XP won't live forever. Microsoft will retire Windows XP from all support in April 2014, forcing businesses to abandon it or risk running an operating system vulnerable to attack.

Yeah yeah, it's a ComputerWorld article on a Gartner report, but it's just too funny not to bookmark. Ah, the joys of proprietary, nonstandard software.
