Let's break it down even smaller. The following guy had more sales on Linux than Mac, 16%.
Defender's Quest
Yes more people use Windows, but when XP and 7 finally have their support ended, the people using those Microsoft platforms will be forced into using precisely what they are avoiding, the 'modern' interface. It's going to be interesting to watch if they move to Mac, Linux or suck up to Microsoft and push themselves into that new UI.
Let's say they pushed themselves into that new UI. Now after months and years of using that, they will be hooked into it by Microsoft's hooks. At that point, switching to Mac or Linux would be extremely difficult due to the extreme UI differences. It would be devastating for the future of Linux without a similar UI, that's what worries me. For Linux to have any future, the users of these OS's which support is ending, need to jump in our (Linux) lake and let their feet get wet.
That's how I'm thinking, it may be difficult for some to understand what I mean. In any case, Defender's Quest shows that there is money in the Platform.
