Yes very smart move, merto really go a bad rap from haters, when in fact its the fastest and best os they have created.... because of the forced metro and no start button people trashed it.
As an os it is fantastic, their only problem was they forced the metro on desktops when they should have made it a choice.
Make it all one system is a brilliant move make it free to manufactures is an even better one. As i understand it manufactures have pay penitent rights to MS for Android OS, this will really hurt android and apple now that they offer it for free.
