Windows will be free on phones, small tablets
Microsoft makes Windows free on phones, small tablets, and gizmos - but not PCs | PCWorld
So Microsoft is making Windows 8.1 free for device manufacturers. Microsoft is doing so many things to increase the adoption rate while blackberry is doing the exact opposite. (breaking up with t-mobile, focusing on OS7, etc). The 8.1 update is massive/feature-rich and Microsoft has solid hardware partners to back them up. So looks like BB has a lot of catching up to do.
