In addition to Macintosh users and Linux on a lot of servers (and the occasional ultra-geek who uses Linux on the desktop), there’s a lot of technology out there where Microsoft doesn’t have a dominant market position:
- Cell phones (WinCE is a niche player)
- Portable book readers (Kindle, iPad, etc.)
- Car computer systems
- Servers (While there is IIS and Exchange, Microsoft can’t undersell Linux, BSD, etc.)
- Dedicated video game consoles (There is the Xbox, but it has to compete with the Playstation and whatever console Nintendo has)
- DVD and Blu-ray players, as well as stereo systems and DVRs
- GPS navigators
The idea that Microsoft controls computing and how people use computers is a rather silly idea.
