I'm most excited about the built-in GPS and music streaming, which would mean I can track my runs and listen to music without my phone. GPS watches cost $300+ anyway so this isn't a stretch.
I’m in the same boat. I’ve always been rather 'meh' about the watch - the only really useful thing I’ve found in a smart watch was the ability to display notifications on the wrist.
However with the addition of cellular data (and if it works as advertised and has reasonable battery life) it does rather .... exciting.
No! I am excited for both as I've been sucking every last breath from my iPhone 5 waiting for this phone heh. But the watch to me is awesome. It's actually what I would have liked to see in the series one regarding cellular. It's now a dick Tracy watch! I'm ordering two for me and the wife.
