I don't think that's how Apple would like to achieve with their first watch. I think, rather than emphasize on how many things it could do, Apple would promote it as, how can you live without it.
Imagine how easy it is to: communicate with a touch, quick reassurance you are alright to your loved one, pay something, a glance of what's important...
These things may sound ordinary and so mundane (we Tech people always wanting something futuristic, but this aint it). However, once a person 'used to' do certain things, it becomes habit, and eventually become something that you can't live without.
That's how I foresee the first gen of Apple Watch is. It's just my 2c though, I might be wrong
