Updated Review
I gave a review after the first couple of weeks with the phone, and now have been using it daily for about 6 weeks and wanted to share my updated review.
Some quick notes about my usage...
I am on the release ring of updates (so no insider/fast ring updates for me). I only use one phone at a time so I stick with the regular release cycle. (thank you to all of you who do get the insider builds and provide feedback to MS).
I use Cricket as my carrier (AT&T towers).
I am in Maryland, so cell reception is generally pretty good for all carriers.
The Great:
Build Quality: This is one area that I personally think can't be overstated. This phone looks and feels as good as any other phone I have seen and better than most. I like it much better than the iPhone 6's I've seen and held, and better than the Samsung's as well.
Display: What can I say, the 5.5" screen is right in the sweet spot for size, the display colors and sharpness are fantastic. Additionally the screen size to phone size is outstanding, my phone is only slightly larger than a lot of 5" screen phones.
Responsiveness: With the Snapdragon 820 and 4GB RAM, this phone is quick. I have not noticed any lagging.
Reception: I live in a pretty high reception area, but this phone does an excellent job. The building I work in is notorious for poor cell phone reception, I get the best of any of my colleagues.
The Good:
Camera: I am not a big photography guy... But for me in every day use it more than gets the job done. It takes pretty detailed and clear pictures. I do think the shutter speed when taking a picture could be improved, hopefully we get a firmware update for that.
Speakers: They are definitely an upgrade over my last phone, and have performed well in calls and watching some videos.
Button Placement: I like having the power button and volume buttons opposite of each other, makes for easy screen captures. Using double-tap to sleep keeps me from accidental screen shots as I don't use the power button to put the phone to sleep.
The OK/Complaints - Admittedly some of these may be more Windows 10 issues than Idol 4s issues.
Camera Button: Having this button in the middle of the phone is not optimal. Maybe the position makes more sense in the Android version where it has more uses... But in the end this is not a big deal, just a minor nit.
Step counting: This is my biggest complaint. I do not have band (MS, Fitbit, etc..) and I don't really want one. But having my phone count steps for me was a feature that I used daily on my Lumia. I really wish this phone supported it.

Bluetooth: This may be a Windows 10 thing, but... Cortana when connected to my car Bluetooth will offer to read text messages, I use it a lot. However on my Lumia (Win 8.1) if I were to receive multiple messages at the same time it would read one and ignore the other. On this phone and Win 10 Cortana talks over herself and offers to read both, or offers to read the other while I am still listening or replying to the first. This then horks the entire process and no more automatic reading will occur until the call ends and a new message comes in. This can be very frustrating.
Fingerprint Scanner: When it works it is great, but I'm guessing my hit rate is somewhere around 60%. It fails to unlock my phone often enough for me to be bugged by it. I should probably re-register my fingerprints and try again. One other nit is I wish it would wake the screen when Windows Hello is blocked.
Overall:
I give this phone a very high rating and would definitely recommend it. To me this is one of the best phones on the market and you can't go wrong getting one.
