Probably safe to say it's lower like under $100 and probably closer to $60.
You know, I'm a hearing aid audiologist, and I used to be an expert 'question answerer' on a forum for people experiencing hearing loss.
I used to see this kind of nonsense all the time about the cost of hearing aids. People writing that they could design one in their shed and sell it for $50 etc.
Life is never that simple. It isn't about what Apple can make each unit for. How many millions did it cost them to go from, let's make an iWatch to look here's the Apple Watch.
There had to be dozens of prototypes, mock ups, 3D printing, dozens of people with salaries and benefits, and paid time off.
Then there was setting up an entire manufacturing process from how to make the sapphire crystal fit so perfectly, to how to get force push to work. The exact process to go from raw materials to a finished case. Then coming up with an entire manufacturing process that can produce these items on the kind of scale Apple need.
Have you ever watched Shark Tank? Some of the entrepreneurs who have invented a widget have often spent $500K or more to go from initial concept to a working prototype. In the case of the Apple Watch the cost of getting to where Apple are today with this project must be astronomical.
So even if it were indeed possible to mass produce this device for $60, which I do not on any level believe. They still need to raise enough money from the sale of this product to pay for all of the development costs, while coving their overheads. They are dedicating millions of dollars to repurpose part of their stores for this launch, training thousands of employees. That also has a cost. Some accountant at some point had to figure how many square feet of space they are taking up in their stores with this product, and how much revenue per square foot they can generate. Some justification has to be made regarding the investment in the training and space in the store.
I could continue, but hopefully you get my point. The products we buy in stores are marked up. That mark up pays for all kinds of hidden costs from advertising and marketing, employee costs, general overhead costs, supply chain, development, packaging, theft, insurance, wastage, and much much more.
If Apple sold their product for the prices you think they should, then they would eventually go broke.
I for one want to see Apple succeed. I want them to make a healthy profit. If Apple is a strong company then they can support the products I have bought. I get nice things like free OS updates. Remember when Microsoft ruled the world, and thought they could charge $150 every couple of years for a new OS? And every other one sucked?
So unless you're the CFO of Apple, your opinion as to Apple pricing and mark up is as silly as me trying to teach you how to fly a space ship, when I've never flown one.
