Default [Q] How exactly is Windows free??

Hi guys,

I just read that they announced in the dev conference that windows will be free for 9" and less..

I am not able to confirm if this is for WP or x86 full blown Windows.?

If it includes Full Windows, where do the 8" tablets like dell venue 8 pro stand?

Also I keep hearing it as widows with bing or internet of things.. isn't this basically an arm version or WP again?? or is it a re-branded RT version?

Whats the point of it??

Or are they basically trying to say WP is free for manufacturers while full Windows is still chargeable??
