I would like to add a few hits of Microsoft from a developer’s perspective after checking out the hits and misses linked on your website and mentioned in podcast.
The most noteworthy and less known are:
1. Microsoft Windows Server 2000
2. Microsoft Sharepoint
3. Microsoft SQL Server
4. Microsoft Visual Studio

These products were actually the most innovative ones from Microsoft for the developers community point of view. I think had to be mentioned in their hits section.

Thanks,

Ashraf
