There are some public bodies, here in the UK, that are not just locked into IE, but to IE6, because the bespoke apps written in the "naughties", won't be updated. The firm responsible, knowing they have said body over a barrel, are pushing for an outrageous fee to update.
(As an aside, it appears, finally, that the management are going to 'do something' not because of the MASSIVE security flaws, us in IT have been pounding into their skulls over the last few years, but various sites 'don't look right'.... *sigh*)
