More specifically: if we ship 125 units, we lose roughly ~$5K per headset. If we ship 250 units, we lose roughly ~$2K per headset. If we ship 1,250 units, we're operating at a slight profit with a couple of years of runway. If we ship 10,000 units, our margins approach 45% (at least on our pure hardware offering; we'd like to layer in some software offerings as well).
Unfortunately, the most costly part of the project is the very beginning. But we think these sales targets are doable if we're able to get our operation off the ground (with customers able to see shipped units being used to replace laptops in the wild).
