So...here's the thing:
The

Watch is not a standalone device. Regardless of Dev Pissing and Moaning (I read it everyday on the apple dev forums) there is literally NOTHING stopping a developer from writing an app that controls a device or thing via an api over the web or whatever.
People are complaining about "crippled" apps and whatnot simply because coders are *notoriously lazy* and unimaginative. I do it for a living and run into it constantly.
Since the watch requires an iPhone...which has a bigger battery, faster processor, etc, and is *by design* a companion device *not in any way* meant to replace an iPhone (such a notion would be absurd) it would be a waste *not* to pawn the heavy lifting off to the pocket-sized 64bit computer people are carrying around.
And believe me, many of the ideas people have been kicking around that 'can't be made' are so...lame...so...predictable that Apple is to be congratulated for culling this stuff by not making it possible to do.
Apple has stated (repeatedly) that they expect most interactions to be short, concise, uncluttered and to the point.
Know this: when the

Watch launches, there will be far more stuff, good stuff ready and shipping for it than the 200-ish or so Wear Apps on the Play Store.
There are some folks doing things to extend their iPhone apps onto the Watch that will make their customers/users happy and more productive.
There are also people that want to make me-too pedometers, "heart rate monitors"..."gps trackers" and other clones of the bundled apps that are going to be left by the wayside.
Don't listen to them. The people that aren't complaining are the ones you need to keep an eye on.
