I think it's about biosensors more than notifications. I love the promise of it and have been an admirer from afar. I have been a hold-out. but will probably buy this next version.
I think it's cool and I see the future and potential of it. It's a nascent device with further miniaturization and tech waiting for it and future iDevices.
Just like the iPhone, when all the pieces were in place, it blew up!
I see the same for the Watch.
I did say the notifications can only go so far,
Which is why I indicated health sensors are the future for the Apple Watch. Revamped software and notifications are not enough to carry the Watch in the future. The health portion is what seems to be drawing a larger audience and motivates those to stay active. That's what Apple wants.
