Microsoft has listened to users in Windows 10, and it's going to be free for phones so it's going to take market share from Android phone producers. Windows 10 will run Android apps and you could use a Bluetooth keyboard/mouse and have a full PC on your phone. I don't want to make any predictions but I'm quite certain the landscape is changing, and they have huge resources to carry forward. Don't count them out of the mobile/wearables market yet.
