Will we have to have a copy of IE 6 to test for backwards compatibility?

IE 7 is only available for XP (and Vista). There still are quite a number of users out there working with IE 6 on 98, ME or 2000, who cannot upgrade their browsers, so IE 6 will probably keep some market share.

That means it's definitely worthwhile to keep testing your sites on IE 6.
