[Samsung Gear S] sbrownla:
just a few things

Very thorough. Just a few things.

Facebook [Notifications]: I've been playing around with the Tizen for Wearables SDK (software development kit). The Gear S and Gear devices employ something called Rich Notifications. What has to happen in order for Facebook to be able to provide more detailed information and interactivity for notifications that are pushed to the Gear S, is that Facebook (and the rest) need to update their app with the ability to work with Rich Notifications. The same goes for each and every other Android app developer/company. But ... whether they do that is up to them. If they don't see any value in it (if none of their users are asking for it, but are instead blaming Samsung--not saying you are at all), then they won't do it.

Lock pattern: There is a setting in Gear Manager on your phone that allows it. Open Gear Manager, scroll to the bottom and choose Settings. Scroll half-way down to Auto Lock and check the box.

Schedule: This is one of the Gear S's shortcomings. We used to be able to "add an event" using S-Voice on other Gear devices, but for some reason we can't with the Gear S. I can see all of the events on my calendar, but only because I use S-Planner. If you aren't using S-Planner, then your calendar won't "sync" with what's on the Gear S. The same goes for texts, email, and some other things. If you aren't using the TouchWiz (stock Samsung apps on the phone), then it won't play so nice with the Gear S. Same thing goes for using Samsung calendar and text messaging while owning and using an Android Wear device. Google has closed down what can be used fully with Android Wear, to their proprietary apps. The rest have limited functionality and display the same "Send to Phone" message to do anything interactive. That may change for both Samsung and Google, since they are starting to open up and release their SDKs, but while Samsung is opening up, Google is starting to tighten up.

Email: I think Samsung is working out the kinks with the Email situation ... but it could be a moment. The email app on the device isn't quite a stand-alone email application. When you add email accounts (e.g., corporate Exchange, which is what I do) through Gear Manager, for example, it also adds it to your phone ... so it's a bit of a challenge. The problem I have is that with it, I can't reply to or compose new email messages, though others with newer phones like the S5 and Note 4 can. There's a combination of Galaxy device model version, Android version, and Stock Email app version that causes variance in the available features when it comes to email. And it's aggravating. But we'll just have to wait and see what happens.

I didn't use use Android Wear for long, but while I did I found it to be too much like having Google Now on my wrist, and not enough of it being an actual extension of my phone or a productivity device. I don't know if that makes any sense ... But I did sell it after a few weeks of use because I found it to be of minimal use. Your mileage will certainly vary, but if you have the opportunity you should try to play around with an Android Wear device. You may be surprised. I won't say whether that will be positively or negatively ... but do try to check it out.
