Internet Explorer 7 will be delivered in final form soon (possibly tomorrow), and it will be installed automatically on everyone’s computers through Automatic Updates shortly thereafter. You may wake up one morning soon and be greeted by a different IE interface. Don’t panic!
Everyone’s attention is caught first by the little things. For me, the IE7 home button is in the wrong place, the back button is too small, the refresh button is in an odd place. I’ve gotten used to those pretty quickly, as always with interface changes, and now I’m more focused on the important security improvements and, of course, the single most important step forward: pages are automatically scaled for printing so the right side won’t be cut off.
