Rather than taking their lead and improving the product, they just sat there with the exact same product for like 10+ years. It was outrageous.I think that this is actually the only viable strategy for a hardware product company in the current world.
As soon as your product is successful, it will be cloned by dozens of Chinese companies and dumped on the market everywhere. Any update you make from there on out will immediately be folded into all those products selling for 10% what you do. In a couple years, they'll all be better than yours, and still way cheaper.
So you have to do the Roomba thing or the GoPro thing, where you iterate behind the scenes until your thing is amazing, release it with a big Hollywood launch, get it turned into the noun and verb for your product category and the action that it does.
But then you have to do what those companies didn't do: Fire everybody and rake in as much cash as possible before the inevitable flood of clones drowns you.
I have a few really good hardware ideas, but I don't believe I could ever market them fast enough and far enough to make it worth spending the R&D to make them happen.
