people will find and use it. Don't make power users spend untold hours getting their systems back to a state they are comfortable with. Don't make computer novices feel lost. Of course, with that "compelling" philosophy, Microsoft would have had a hard time selling anything over the years.

I'd bet the main consideration Microsoft has for many of its changes are to drive recertification income and how-to books. They don't make as much money if people pass the tests the first time, and they are harder to pass if you have to know multiple operating systems.

I don't need an address bar (IE7) that takes up most of a toolbar. I know how to scroll if I need to. I also don't need a search box that duplicates my Google toolbar search. Give me the option to turn it off and put something useful there.
