I see and agree that an equal sized hardware and software component compared, the hardware will be harder to develop and more expensive. I don't think from a project perspective this holds true though, since the amounts are often something like 1 hardware to 10 software or even more. But your argument still holds true in that iterations are quicker and easier to achieve, which is also why this factor will only increase.
