> If only 10% of those users are developers

Your overall point stands on its own but are you really trying to argue that 1 in 10 PCs are software development workstations?

Also, you should not expect that having a 90% market share overall will translate into 90% market share among any particular subset of users.

No, I'm not. My point is to only draw an illustration of just how small the overall marketshare for "non-Windows PC users" actually is. I go out to meetups all the time and everyone wants to act like I'm some sort of weird outlier because I'm the only person with a Windows machine in the room.
