I've often heard the claim that the startup graveyard is full of great products that didn't succeed (e.g. because the startup wasn't good enough on marketing, or because they didn't solve a big enough problem).
What are some examples of this?
If there are examples of truly great products that eventually died, I'd like to study them more in-depth.
I'm not entirely sure what caused their death, but my personal view is that they tried to become too big, and I don't think the wearables market is really that valuable. They could have remained a small house which maintained a great product for a segment of the market that really appreciated it. I'm sure that's a simplistic view, and definitely ill-informed since I wasn't on the inside.
I still think they are far better than the Apple Watch or any of the Android Wear devices I've seen.
