Is it just me, or are there really people who are answering "yes" to some of these questions?
Why would you limit yourself to those poor features for a watch? Because it helps your point?
There are many, many real life advantages that an iWatch could provide. Even saying "It can provide you with an easy way to view notifications, who's calling, etc without pulling out your phone" is a very limited way of looking at what is capable with an iWatch/wearable computing.
Biometric security/password protection- Wouldn't it be great if just weaing your iWatch, it would automatically log you in to your iPhone, Mac, passwords in safari, etc. Maybe eventually even things like cars and homes
NFC- whether it be for payment or those "tags" that you can tap to change environmental settings. It is a significant improvement to simply tap your wrist (and no password required, thanks biometrics!) than to get out your phone, tap it, and enter a password.
Fitness monitoring- things like the nike fuelband are already getting popular.
Hand gestures- Apple TV is going to become a thing. Wearing the iWatch could allow you to control it through simple handgestures. They could also be used for some games
convenience- there are some times when it would be much easier to look at/interact with your watch then getting out your phone.
There are certainly much more possible, but that is only the beginning of what I can think of. Now, I wouldn't expect all of that to be in a 1.0 product, but there certainly are some real opportunities here
