I just installed IE 7 on my home server and tried it out. Let me say bluntly that I hate it. The UI is very different and I don't seem to have any option to move bars around. No, I don't mean the 'extra' bars like the Google toolbar or links. I'm talking about the standard toolbars that every browser has and needs. The file/edit/view options are not on top where they are in just about every Microsoft product. The home/page and other buttons are thrown all the way down and to the right of the new tab bar and the url entry form is right on top. This configuration sucks.
Maybe I'm totally wrong. Maybe Microsoft spent a billion dollars to poll average, non-programming people and found out that this is the layout they want. Maybe this is better for productivity in a business environment. Maybe I'm just in User Interface shock because of the radical change.
Bottom line is that I'm really not impressed and I doubt that the people who visit my site will be either. I've seen a very stead shrinking of the IE marketshare and this new version of IE feels very much too little, too late.
