Windows Phone / RT System Will Be Free ?

This morning we read a news about Microsoft is considering making Windows Phone and Windows RT system free of charge.

I think it is not bad because most of phone makers are using free mobile OS system Android. another non-free mobile OS system is Apple OS but people like Apple, so the market shares of Android and Apple OS are much bigger than Windows Phone / RT, it doesn’t make sense if Microsoft still charge Windows Phone / RT from device makers. also, Microsoft owns Nokia mobile department now, and Nokia has the most big Windows phone market share at present.
