How so? Hardware startups have been bought before. This isn't a unique event. I worked for a hardware startup for a couple of years and VCs being cautious about the category is very well deserved. It is easily an order of magnitude harder to develop a successful hardware product than a success software product. And even after you've sold a million of them a design defect could show itself that makes all million of them break and destroys your entire company overnight. It's doable but very hard.
