Samsung's Project Orbis: A Risky Apple Watch Challenger
Well, it's certainly nice to hear about a wearable device other than the Apple Watch for a change! I appreciate the media spectacle it's drumming up, but that stands to give wearables' profile at large a nice boost - and it's just one in a sea of devices. The 'Orbis' looks cool (and I mean that literally), but I suspect it will have the same problem as most other wearables if Samsung can't get the price down - low adoption. This in turn leads to low interest from developers (they need to see those dollar signs), low quality of apps, and lower adoption still. Considering how dependant on tethering to an existing smartphone they tend to be, I just don't see where smartwatches fit into most consumers' budgets.
You didn't mention Bluetooth, but it looks from the early documents like we already know that the Orbis supports it. Personally, I always appreciated that those square designs offered a little extra screen real estate to open up readability of a wide variety of apps. After all, it's not really a watch, and I can't help but feel the smaller, circle screen might constrain what developers can get working within the viewing area. I'm also skeptical of interfaces that try to be what I'll call 'overly' intuitive. I was never much into Apple's "wheel" interface on old iPods. It's hard to know without seeing it for myself (and I did sign up for the SDK), but I feel like the bezel interface might, again, pigeonhole developers into just the most straightforward of apps. As you point out, that app ecosystem determines the Orbis' future, so these may be more than minor quibbles.
