The governments (Great Britain, Argentina, most of Los Angeles) tested IE as the default browser (I mean not the charter, but the whole country) with IE6 and have never been updated for almost ten years? and Windows XP is by far the most installed OS in the world, with ie6 sp1 as the main browser.
ie6 will be here until 2014 for end users and for governments, I would add 5 more (at least in Los Angeles).
will there be peace by then? who knows, will make your work easier. at any cost. will your client plus $$ for your ie6 version? ttt.
On the other hand, you could cause losses for the client, because visitors navigate www with outdated software and you no longer support ie6?
Its a cyber-educational thing, people once realize (perhaps before 2014) that the browser is not a folder.
