I'm starting to realize how awkward it would be to sit across from someone with one of these for a meal or on a date, and watching the notifications go off the whole time. Instead of a phone that can be put away, or flipped over on the table, now the person would constantly be looking down at their watch every time it wakes up from a notification, and you would be able to see it as well. Imagine a restaurant full of people wearing apple watches.
Let me guess, you've just seen a video...
BTW, nobody wants all their notifications going to their watch, that's why you can filter them. Unlike on the phone, the notifications can be silent and indicate who called through silent vibrations (taptic), you don't even need to look down if its not important.
You can also stop receiving notifications on the watch if you don't want too ("same as putting it away"). Good to see you're building a straw man instead of snow man, with the warm weather coming and all...
