It's beautiful, if the marketing site is to be believed. However, a couple of glaring things I see:
The cuff looks pretty rigid, which would mean people to either side of the ideal designed-for body type would have a less than desirable experience: the cuff either digging into their wrist or dangling from it. If this isn't the case, it should be clarified further on the marketing site.
Do I have to carry an extra cell phone-sized block in my pocket just to use the watch? The site didn't make that very clear. If so, where's the advantage over just carrying your smartphone that justifies carrying the extra component?
Very interesting and fairly attractive for essentially being a featureless black cuff. Should it actually come to market, I'm sure it will be divisive.
The marketing though is pretty bad.
Why 'Hub'? The word 'hub' has a very stationary connotation, which isn't at all what I'd associate with a wearable.
WTF is a 'pocket screen'?
Is this thing supposed to replace my smartphone or work in tandem with it? I'm assuming it's the former, but that's such a radical departure from what most people think a smartwatch is that a little education (in the context of the current technology market) about the product would go a long way.
Really, there's almost a 0% chance of me getting this, because third-party app support is going to be a nightmare. Running the already terrible Android Facebook app on my wrist sounds like torture.
I think in the current state of chip and battery technology, this prob won't work out that well. If the watch is the "main" hub with GPS and primary way to power and interact with everything, I have doubts about battery life. Not to mention the usability nightmare of running full on apps on the flexible tiny screen.
I do believe that eventually in the future, the watch will be the primary personal computing device - like the phone is now - and every other devices will pull in info from there. We just need the battery tech and interface design (we need few years to get used to designing + building software for tiny screens) to reach there.
This band/watch is a little ahead of its time and successful products are about the right timing as much as being a product itself.
