I have always wondered how the Apple Watch detects AFib? Does it require a special sensor, other than the heart rate sensor? If not then why don't all smart bands/smart watches with heart rate sensor detect AFib? 

So, if you take a look at the notification in the picture in the article, what it says is that it has detected irregular heart rhythm "suggestive of atrial fibrillation" so not officially "detecting" or diagnosing AFib but rather notifying you of something that has been detected that may be AFib. And yes, as far as I can tell it is just based on the heart rate sensor. In the health app in the section about irregular rhythm notifications it says "Apple Watch can notify you if it sees your heart beating with an irregular rhythm that may be atrial fibrillation." In "How it works" it says "Apple Watch will occasionally look at your heart beat to check for an irregular rhythm that may be AFib." Also says elsewhere "Apple Watch is not constantly looking for AFib. This means Apple Watch cannot detect all instances of AFib, and people with AFib may not get a notification." And "If you receive a notification, Apple Watch identified an irregular heart rhythm that may be AFib and confirmed it with multiple readings." 
About that last part, I can't find the exact wording right now, but I seem to remember reading something about how if it gets this kind of reading a certain number of times within a day or whatever then you'll get the notification. So it's not just if it gets a high reading once. I got the notification one day when I had been experiencing noticeable heart rate irregularity all day. Got the notification late in the evening. In the data it shows me five different readings that it collected over about an 8 hour period before it gave me the notification. And yes I have since seen my doctor about it and things seem to be fine for now
But all in all I think it is just based on heart rate data that it collects methodically and notifies you that it "MAY BE" AFib if it gets what it thinks is enough data over a period of time to make that suggestion.

So, I'll probably shop for a used SE for my wife who needs to upgrade from a 5S and doesn't want to go bigger. I figure if she's getting by on a 5S now, an SE should still be pretty good for her for at least a couple more years (and then she may just have to face the inevitable, unless Apple does surprise us with a new smaller phone by some miracle).
My question for the collective intelligence is what should I expect the SE market to do now? Will retailers start selling them off cheap and maybe I should be looking at new for a good deal? Or will prices hold as now they're in limited supply (I guess we don't fully know if Apple is still making them and just not selling them themselves or if they've stopped production for the U.S. market)? And with the used market, will people be offloading them at lower prices as a now older and discontinued model, or will prices start to actually creep up since demand in the used market might be greater coming from those who were waiting for an upgrade but now scrambling to snatch up what remains of the last good small phone?
Thoughts before I buy?

So tough to deal with the watch when you are drenched in a humid day after a run. Just stopping the activity is rough. They have to work on that sort of thing, no matter what the technology. 

Press on the crown & side button at the same time to pause it. Wipe your hand, then stop your workout any time you’d like. 

Really? Huh, good to know. Guessing this is just for Apples Workout app right? I use Strava and would love to have a physical pause button for these sweaty situations and for winter when my “touchscreen” gloves aren’t playing nice. I’ve considered switching to Apples’ app. The UI looks great and I generally just like to use first party solutions when possible. The holdback with Workout though is the lack of a web portal or something like that for viewing stats, running reports, etc. unless I’m missing something. From what I can tell it just dumps them into Activity and the info you can view there is pretty limited
