Innovation is generally incremental. The iPod was not the first MP3 player; they just perfected it. The same is true of many MSFT products.
Microsoft just made the first FULL desktop OS capable of running on all devices including touch based tablets, and you find that to be a bad move?
Microsoft also unified the computer market with Windows back in the 1990s. Before that, it was sheer chaos and incompatibility. Windows and FAT32 gave the world a standard.
While many people dislike it, Microsoft Office was the first complete and integrated office suite to include all the functions needed in an average office. It took it some years to get good, but now it's the standard.
Windows 95 gave us real multitasking at a time when you could freeze a Macintosh by holding down the mouse button.
Come to think of it, the 'softies have done a lot of good things.
And then there's Microsoft Research and Microsoft Press.
