I don't know.. I don't use iPhones anymore (for software compatibility and price reasons - on a Spanish salary they are simply too expensive) but if Samsung would get a similar feature then perhaps...

It depends how well it works though. And how much fussing around is actually required with that targeting stuff. Of course in an emergency I may not always be able to fuss with it a lot. It depends on real-world usability. I'm sure the various hiking sites will put it to the test when it comes out.
