Microsoft Corporation (MSFT:NYSE) is know more of a follower than a leader. Look at it's major products, they are as a reaction to an existing product.

Examples:

Microsoft Office (Wordperfect, Aldus PageMaker, Lotus 1-2-3, Borland Quattro Pro), Windows (Macintosh), MS-DOS (PC-DOS), Xbox (Sony Playstation, Nintendo), Internet Explorer (Netscape Navigator), Windows Phone OS (Apple OS, Palm OS), Zune (iPod), and so on as the list is endless.

Now tell me a something Microsoft does and I will tell you who is the real innovator.
