I agree about the battery, but I will say that what it can do now the battery life is pretty good. FYI there is a flashlight function now. A software update should be able to address the music streaming and improve sir functionality. As far as the camera goes, I just don't see that happening. Independent set up isn't that high on my list of wants and it doesn't appear to be that high on Apple's as well.
the "flashlight" function is better than nothing, but no replacement of a real flashlight. and, using the whole screen it sucks battery like crazy. still, that's the least important thing on my list and won't happen without a camera.
afaik, battery life is fine, as long as you don't use it exclusively as an iphone replacement. doing siri, music, calls, messages... over LTE won't last you a day. it wouldn't need independent setup, but it should work without an iphone (e.g. with an ipad, mac,...), because I`d hope to replace my phone with it. that's also why it'd need a camera for scanning things and making quick snapshots. but i don't see that happening in the near future either. still, the camera is the only "real" reason why it couldn't completely replace an iphone for me. (again, for bigscreen apps like safari or games i'd use an ipad anyway - i hate fiddling around on a tiny phone screen). but i could carry a camera like a sony a7s instead of an iphone and have the best of both worlds...
independent music streaming will come, but I guess right now that limit to apple music is also in part there to preserve battery life. as for siri - that's on the server side anyway and sort of independent from the watch. still, siri needs so get better. on the other hand, it has to be even better for a device without a big screen and a (software) keyboard.
