Those emojis still really look out of place.
The only thing that worries me about this product, is that there isn't any mention of battery life.
Latest claims by Tim Cook suggest that it should basically last throughout the day, and you would need to charge it over night every day, unless you don't use all of its features, in which case it could last up to 3-5 days.
I doubt even Apple knows the exact numbers.

They are likely still tuning the daylights out of the software. One of the fantastic things about the watch is that the battery life improvements will flow through to iOS and OSX.

This looks super gimicky
What will be interesting for me is to see whether Apple and or the Apple Watch is going to "up the game" in regards to the whole wearable technology thing. I mean there have been and currently are many Android and other watches but they're not much better. It might take a few iterations before they really nail it. First thing is to ditch the wired-charging. I can't get over the idea of plugging a cable into my watch at night.
It uses inductive charging.
Could these things automatically detect heart attacks, and alert emergency services? Obviously a human in the loop, before it calls emergency services.
It's not out yet, but I believe that it is not monitoring your heart rate continuously, because it would require the IR leds on the back to be on at all times, which would drain the battery.
Probably need some kind of sampling method, rather than continious.
Fitbit Charge HR works exactly that way - the IR leds on the back are constantly on....even when I take it off they keep on blinking. And it works for 4-5 days. Obviously it doesn't have a huge screen like the Apple Watch does, but it's certainly possible to be monitoring the heartrate constantly.
If the Android watches are anything to go by, absolutely not. The heart rate monitor on my Moto360 is often out by 50% or more.
It is irrelevant whether they can or not.

The FDA and other health agencies have made it crystal clear that these devices are allowed to provide health guidance only and not be used for anything critical to life.

If someone bought the watch for this feature and it didn't work Apple would be in serious trouble.

So what is the battery life? Rumours stated 3-4 hours.
Are we posting advertisements on HN nowadays? ;) This page has been around since at least December. There's also no new information that was not extensively discussed after the Apple keynote.

Or did I miss something?

Somebody found out it wasn't posted before I guess.

I hadn't seen it before so I upvoted it.

Same for a bunch of other guys I guess.

Regarding advertisements: I'm fine with them as long as they are interesting. Also, quite a lot of the stuff you see on HN is advertising, -advertising for someones consulting business, SAAS offering etc..

I had a Moto 360 for a while, until I realized I didn't want the features. All I need are notifications sent to a tiny screen on my wrist. And the Apple watch has 1000 more features than Wear. I think I'm going to be very happy with my Pebble for a very long time.
I miss the old Apple. The old innovative Apple that transformed music and turned smartphones on their head. The Apple that didn't release shitty "me-too!" devices. The one that gave a shit about OSX. Remember that Apple? I do. How I wish those days would return. We miss you, Steve :(
