Ask about the 20% or so of users who still use IE6 in a development environment and there’ll be a lot of rolling of eyes and general muttering.

The point is, until usage figures drop low enough to justify ignoring them, your dev team will still need to code, and you will still need to test, web sites in IE6. We’d all like them to upgrade but wishing it won’t make it true. Unless you’re in the privileged position where a client comes to you and states “make my site work only in IE7 and above”, you can’t afford to lose a fifth of your audience. But that’s exactly why no-one will ever come to you with those requirements!

It’s here for another couple of years yet. Grin and bear it.
