Indeed. XP itself is a major reason IE6 hangs around so much. XP installation discs and images only ever came with IE6, never anything newer. And with the frequency that most corporate workstations get reassigned and recreated and reinstalled, IE6 comes out of its casket all the time. It's not that these corps are scared or ignorant of upgrading past IE6, it's that doing so across 100 or 10,000 machines is a huge task and not worthwhile from a cost-benefit standpoint.
Have you ever worked in that sort of environment? "doing so across 100 or 10,000 machines is a huge task and not worthwhile from a cost-benefit standpoint" contradicts my own experiences.
AFAIK IE 5.01 on Windows 2000 was supported until the end of support of Win2000, despite the fact it was dying by 2005 or so, exactly because it was bundled with Win2000.
