Taptic feedback. Diversity in product design. Digital touch. Architecture of Apps.

Those are all unique to Apple's Watch as is pretty much every aspect of the look & feel. You can argue different watches having the same features but Apple's implementation will always be quite unique.

Well, the heart-rate monitor for starters (and I suspect, based on the optical design of it, that it was built with an eye toward measuring blood oxygen content in future incarnations). Extant activity trackers on the market don't really do it for me from a value standpoint--but I do own a Garmin cycling GPS. The Apple Watch also has enough computational oompf that they should be able to implement Suunto's Firstbeat HR algorithm for better calorie burn estimation (this is all speculative, of course).

Strava is a killer app for those who already have an iPhone: Watch Sport costs about what I would pay to upgrade to the latest Garmin Edge, plus it tracks non-exercise activity (which is something I like but am not willing to pay for by itself). On top of all that, Apple Watch comes with maps (and turn-by-turn directions) for free (something you pay for out the nose with Garmin).

Then there's the mobile payments piece. Taking out your phone is fairly low-friction, but double-tapping a button on your watch and holding it up to a terminal is even less so, plus the idea that I could go out with just my phone and watch is pretty appealing.

I'm not a fan of what I've seen of Apple Watch, or wearables in general, but the UI innovations that Apple has made for a tiny screen feel clear to me. The manner of navigating apps with the crown (and using a crown to navigate, period), is the one that jumps out the most. The casual sketching and heartbeat communication modes are a bit contrived, but novel. Their approach to haptic alerts sounds distinctive and thought-through.

To be clear, I am not a believer in this product, and I really like Apple stuff. But if you're not seeing ideas and improvements, I think a closer look is warranted.

Moving the space app centric is a pretty big deal for me at least. Even if it requires teathering to a phone, and with the performance issues, it's a big step above the notification centric nature of Android Wear. Plus the ability to run on wifi and stay connected with the phone.

Not saying the device isn't worthy of most of its criticisms, but let's not pretend this is and iOS-ified version of Android Wear.

Taptic feedback and force touch come to mind, but let's get our hands on it before drawing any conclusions.
