Hello, I am a Galaxy Note Pro 12.2 user. I am considering to buy the Samsung Gear S now or wait for the iWatch. Two major features that I need are: a) Be able to receive and make phone call via the watch. b) Notify me whenever incoming message or phone call arrive. Better if it can also show calendar on my Android device. When the iWatch comes out, will it be compatible with Android devices such as the Galaxy Note series? Will it be able to do Points a to c?
