I'm a web developer for an organisation that builds web based software that is primarily used by UK local government departments.
IE6 is my nemesis.
A lot of these local authorities are slowly starting to upgrade to Win7 platforms (just in time for Win8), but just like a chain being only as strong as it's weakest link, we have to ensure we are developing for the slowest common denominator.
From the dozens of conversations I've had with Council IT teams around the country, it isn't a lack of will or of motivation or of education, but of a real (and partially justified) fear that if they upgrade to Win7, some essential legacy web based application that works flawlessly in IE6 and XP, will fall over when introduced to IE8. This has happened at various places around the country and has cost Councils a pile of money to fix the issue or to replace those legacy systems. In the post recession cost-cutting world, no one wants to be the guy who lands their employer with a huge bill. I expect we wont see the stragglers taking up the challenge until austerity is done and dusted.
And there you have it. I managed to make this all the coalition government's fault. My work here is done.
