Ken points us to a survey of Japanese software engineers and 99% of them are Windows users.
I know a lot of talented software and Internet engineers and a sample of my engineer friends would not be 99% Windows.
This says A LOT about Japan. This says to me that Japanese engineers do not understand open source software, do not have hands-on experience with Linux/Unix, etc. You want to know why Japanese companies (esp. Internet businesses) are struggling with engineering talent? The answer is here.
I do have Japanese engineer friends who dual boot Ubuntu and Windows, or are Mac users, etc. but they are clearly not the average.
Just as a monopoly of the browser by IE for years led to the security exploits and spyware, a quasi-monopoly in software development tools by Microsoft has led Japan to the current state of poor software engineering.
Over a third of Japanese engineers won’t use Linux on the desktop � 世論 What Japan Thinks
