Yeah I'm in the same boat. Apple's long hyped device comes out and, oh hum. It is the new 3D TV: a device looking for a purpose. Wow now I have a remote control for my phone when I take selfies. So as long as I have a really stable place to put my $600 phone on and don't mind taking a couple steps away from it (often in public places) I can use my $350 watch to click the snapshot button. Hey look my $400 smartwatch can
The OP: chances are if you are looking for a reason why you could use a new piece of tech you don't need it. You shouldn't start with a product and try to find a place for it in your life, you should start with a problem and if a tech solves it great. You hinted at one: needing to use a phone hands free from a clean room. So how about a bluetooth headset? Your employer doesn't mind you leaving your workspace to take calls all the time? If it is work related can't they supply you with some system to answer emails/phone calls etc in side of the clean room? (Generally I don't spend my own money to solve my employers problems). Lastly prefer Android but will consider Apple: I'd say don't even consider them: from all I saw the Apple watch is meant, and they'll probably fight like crazy to keep it, to only work with Apple phones. The thing is useless without a phone and your phone has to be an iPhone. Unless you have an iPhone but prefer Android for some reason (and if so why do you have the iPhone?) Apple Watch isn't even a possibility.
