Some would have you believe that Apple is the epitome of interface excellence. But Microsoft has been the real interface innovator for the past 5 years or so. Microsoft's Usability Labs have done some incredible research in usability testing, and have overturned some commonly held misconceptions about what "good" interfaces should look like. If you follow this subject at all, you would already know this.
Windows bashers need to lay off and pursue another subject, like Product Activation. Eye candy is simply not the same thing as a good "interface."
You sit 9/10 "average" users down at a computer, and they just GET the Windows user interface. It works, and people don't need to read a manual to figure it out.
Eye candy does NOT equate to a better computer. Apple knows this, but hopes you do not.
