he says your iPhone must already be unlocked for it to work.
Not true. I'm no expert by any stretch but when you say unlocked, my iphone 6+ goes dark after 3 minutes and I need to enter my code to open it up and use it except to answer calls which I rarely do. BUT, when a call comes in or an email, or a text message or a stock price alert, I get it on my watch. This afternoon, I got some photos of my grandkids from my son in law. The watched tapped me on the wrist and I looked down and it was my grandson photo on the watch. Usually at home my iphone sits on my desk in my office. But I take phone calls and and other stuff from my wrist anywhere. If I go to the end of my back yard I lose connection. The BT range on my iphone 6+ and the Apple watch is the best I have ever experienced. This afternoon, I heard thunder, so I opened up the weather map on my watch and saw the storm rolling in on the radar map. I haven't used the Apple Pay feature much yet, mainly because I don't shop much but my wife does and she never has to unlock her iphone 5. Just double press the side button and up pops the CC image, hold to the sensor and feel the tap and it's paid.
I only have a dozen apps installed right now. Even with some 3000 claimed to be available, I don't find anything beyond what I do have yet. From what I have seen that story will change with the wOS2.0 this Fall.
The one app I miss from my Sony that is not yet available on the Apple watch is a flashlight. So, if I need to use the watch as a flashlight, I activate the weather map which lights up the face white. That works but a real flashlight app would be nice.
Some rarely used features I find the watch nice for when I use them is controlling the audio player on the phone. I can access the audio books and control it from the watch. If I want to show a photo to someone, I can display my entire library of images on the iphone, zoom in on the watch display and bring one up full screen.
While this is strictly a personal use and not everybody would find it important, I have my BP cuff that works with the iphone control and logs the data automatically. Later if I want to check something, the BP cuff device now supports the Apple watch and I can bring up the charts and data as well as control the cuff to take my Blood Pressure and check if I am experiencing any atrial fibrillation or flutter. This also ties in the data with I heart app and other health apps for a complete health data base. This can also be sent to the cloud where I can authorize my doctor to receive the data.
I have seen others with Apple watches claim they don't find much use for them too. It becomes quickly obvious to me they just don't care to learn what all it can do. Nor do they want to spend the time to learn. One guy had one for 3 weeks and still didn't know how to access the Home screen and had never customized his watch face. It took it out of the box, paired it and that's it! I am surprised my wife uses so much of it, she never wants to return to a dumb watch. My son-in-law uses his watch to control his iphone 6 camera. I haven't tried that feature yet but he says that's his favorite feature.
Of course, lest I forget, Siri is a great way to just talk to your watch and get the answer on the screen.
I go whole days and never pick up the big iphone 6+. Don't need to! Just need to have it near by. But, I have to be careful because not looking, the iphone battery can get low after a couple days. So, there is an Apple watch app that monitors the iphone battery, so if that gets too low, I get an alert and it tells me to plug in the iphone soon.
