Microsoft keeps a steady logo for the company, and updates the logo for their products. See Windows vs. Vista vs. Windows 7.

Apple doesn't have logos for their products, so they update their company logo instead.

Just different approaches.

I'd beg to differ that Apple doesn't have logos for some of their products. For example:

iTunes - http://www.google.com/images?q=itunes+logo Garageband - http://www.google.com/images?q=garageband+logo

But not all certainly - http://www.google.com/images?q=iPad
