1) Please don't top-post in reply to a bottom-post. It makes the flow of the conversation difficult to read. 2) Please don't post to the list in HTML. Plain-text is preferable. 3) The costs of production were discussed a LOT on this list in the past, when the Openmoko team was still active. To be honest, even if the component is only $1 then it may be too expensive, as many more design and testing costs are added to the total production cost by the addition of the component. Customers will be dissatisfied if it doesn't work as expected. A large increase in market share is needed to make the addition worthwhile. Therefore the addition of a camera may be worthwhile, whereas the addition of a barometric sensor is not. However a camera requires retooling of the Freerunner's case, a surprisingly cost-prohibitive change. I think the cost of creating a new case for the Freerunner is considerably more than $10,000. I would imagine that a camera requires other components to make it work and is more complex from the design point of view. There have historically been two major complaints about the Freerunner - lack of a camera and of 3G. Either might enlarge its market share considerably, but both were rejected on cost grounds. This barometer is self-contained and connected to the i2c bus, a _relatively_ simple addition. If there is demand for the barometer - although I'm inclined to agree with Rask that there wouldn't be - then it might it be justified to add it were Brazil ever to go into Freerunner production. A 1.3mp camera would produce complaints that it's a poor specification compared to the iPhone. Hardly anyone would be grateful for the addition of the barometric sensor. TBH, if the Freerunner were in reliable, long-term production, I might be able to imagine a market for Freerunners amongst hang-glider pilots. I think a person might be able to make a living adding Christoph's sensor and selling Freerunners with varioaltimeter software installed. The software would have to be closed-source, however, to make a livelihood out of it and realistically it might take a year to get the software to an acceptable quality for commercial sales (and still longer to build-up market share). The author might need to write anti-piracy measures into the code, and what is to prevent a determined attacker from patching the kernel to report a different IMEA number to the altimeter software?
