I would love to have call display and notifications with the ability to read text and email preview. Streaming would be fun but not necessary. Just the convenience of not having to pull the iPhone out of your pocket just to see what the vibration was. Seems simple in my mind, but if any of the early release images of the next nano it looks like they just threw a camera on it, really? another device with a camera, seems like they have a pattern.
I hope they come out with a bluetooth watch device, I’d stand in line for it for sure.
