Yeah, that's really not great at all! From their website:
> Wait, it's single use? Yes. We know this sounds a bit odd, but in this particular circumstance we believe it's the best solution to the given set of constraints
I don't want to be too harsh, since it seems like the pebble team are working hard at producing some exciting tech. But intentionally making a single use device is phenomenally irresponsible in today's climate.
I know they say they'll recycle them, but it'd be naive to expect anything other than a tonne of these becoming e-waste.
A phone has 10-20x if not more weight of electronics.
I assume you will use your phone for 20-40 years?
Constraints include needing to keep component cost low and ensuring that they could sell more hardware in 2 years.
I was initially put off by the lack of recharging too, but I've changed my mind a bit.
I think the amount of ewaste is pretty small. My uneducated guess is that it's probably about the same as a musical birthday card. And unlike a singing card that probably gets used a dozen times and thrown away, the Index can be used >10,000 times before it's time to recycle it (assuming it lives up to the specs)
For comparison, check out the rechargable Stream ring. It's bulkier, costs >2x as much (before including subscription... The sub alone costs more than buying an index every 2 years), and needs to be recharged every night. It's sort of in line with Pebbles advantage over other smart watches- doesn't need to sleep on a charger every night
