Not sure about that.......Didn't poo poo that idea of having your phone in another room and notifications? Correct me if I am wrong about that.
I suppose I did - though my example today was with my phone right next to me. I had to answer the call, then switch to speaker phone on the iPhone while I was sitting working on my iMac.
New feature = accept call on iMac without looking at iPhone or moving my hands from the keyboard/track pad. Seems pretty sweet.
But i am not sure about getting double notifications. If i am at my desk as i am now....writing this from my iMac.......with my iPhone right next to me......I get a text......then get 2 notifications....one on my phone....one on my iMac with Yosemite. I think that would annoy me after a while......
Oh I agree completely - that's why I only have my phone numbers associated with my iPhones and not my iPads or Macs. If someone wants to iMessage me via my AppleId, I'll get it on my Macs but otherwise it only pops up on my phone.
Even so, once you clear it in one place, it goes away on the others so its not a huge deal. Again, if your phone isn't in the room you aren't hearing two dings likely anyhow so....
But I've had the exact same thought.
