I didn't think they had a business model that was sustainable.
Kickstarter is a great idea for for putting a toe in a new market or product category, but if you're still relying on it to fund your 2nd/3rd generation products then you might have to accept that you don't have a viable product.
I looked at Pebbles a couple of times - the always-on display and week-long battery life should have been end-of-argument features for a smartwatch, but they always looked a bit cheap and plasticky, and by the time they were actually available to buy, there always seemed to be a better version 'coming soon' (the good old "Osbourne Effect"). They may have been a lot cheaper than other smartwatches but they still needed to look better than a $30 dumbwatch.
Its looking like there's a modest market for smartwatches, but the killer app is fitness tracking, and dedicated trackers like the fitbit do it better, more affordably and in a smaller package that doesn't add 0.5s to your lap time.
Apples comments about "sell through rates" are information-free and neither prove or disprove anything - apart from smelling of freshly-picked cherries.
being popular doesn't necessarily (and quite often is the complete opposite) mean being good.
Unfortunately, electronic products, particularly miniature ones with lots of custom parts, rely on large quantities to be profitable and affordable.
Those are some stone cold rock references.
The avalanche has already started - it is too late for the pebbles to vote - Kosh, Babylon 5.
