Oh, and saying "What's my name" and having Siri respond "Your name is <name>, but since we're friends I get to call you Captain James T Kirk". But that's just personal amusement.

I use it for stuff I forget to buy when I'm shopping, mostly. The stuff you don't buy often, like "remind me to get deodorant when I'm at Kroger."

Also the timer-type reminders/alarms are great.

I really wish it was easier to compose notes and the like. I finally found how to reliably get a newline with the voice keyboard (by saying "period newline"...the period is required).

"Her" was pretty inspiring for all of the voice-related stuff. But I'm still weird about using voice commands in public. If everyone was, I'd get over it.

Seems a lot more suspicious of me for some reason..

Another problem is typified by a commmon Android Wear app which allows you to request a fake phone call on your phone. This example shows one of the use cases for a wearable: its a device you can look at when its socially or physically awkward to pull out a phone. You don't want to say, "Google, this meeting is boring!" But you might want a button that lets you do something about it.

One could get around most of that by being able to set aliases for often used apps, like, "quick open 1." If it's hard to open a seldom used app, it's not that big a deal.

What's fiddly about buttons? It's much faster than swiping a couple of times to get to the option you want.

I agree that there are disadvantages too. One of my jackets does make it harder to access all the buttons. And scrolling through a list one item at a time can be more annoying than just swiping and tapping on the item you want.
