I think IE7 users will upgrade faster than IE6 users for these reasons: 1. The quick release between IE7 and IE8 means that users who have recently upgraded (or have adjusted) to IE7 haven't got stuck in their ways just yet and have recently encountered change. 2. IE7 users have already (tended) to show a willingness to upgrade and learn a new system (either Vista or IE7 on XP). 3. IE8 is being rolled out as a critical update so the willingness and recent experience of change should influence IE7 users more than IE6 users. 4. A major reason for not upgrading IE6 is legacy code written for IE6 - this should be less of an issue on IE7. 5. IE8 isn't nearly as different from IE7 as IE7 is from IE6.
