Hardware is hard imo due to: 1. Cost and pricing models. This is very difficult especially when you're not big enough to place larger production runs. You don't have economies of scale here. It's expensive to manufacture just a few boards at a time. 2. Manufacturing/supply chain points of failure. 3. Hardware points of failure (buggy vendor chips etc.) which could easily derail a project. Hardware isn't as malleable as software too. 4. Long product development times. Your first version of the product can quite easily stretch out to many months or even years. This is a huge risk from a shareholder's perspective.
