Also, put a CAN-transceiver in there and you can use the Jolla as extra console for your car, getting more, and more accurate readings from the car's sensors. Perhaps even tweak settings.
If the main display is OLED or something very akin, I can't see much need for an eInk display. I actually prefer to read books on the N9 at night than on my eInk e-reader...

You have to believe wikipedia. I guess 3.4Mb/s for uFM.

wasn't there also talks about connecting to raspberry pi or arduino directly?

Now when I think about it, most devices are not really designed to be used display-down. And most modern displays don't really have any protective "ridge" around the display, so they are resting directly on the display when put display-down. That could lead to quite some scratches.

Also, I can read comfortable laying on sides or belly, and don't need glasses as it is easier to keep the device close to one's eyes.

For the Jolla OH, an alternative for eInk would be Mirasol, made by... qualcomm. However, the I²C interface might be too slow for this.

Currently this would require specialized and expensive devices, or stand alone. A OH-concept would make it easier to design and cheaper to produce.

Also, the new iPhone 5S has an M7 "motion" coprocessor or whatever it is called. Turns out this is a very low-power Cortex A3 CPU capable of continuously processing movements. The OH could provide the same functionality to the Jolla. I don't know if it is possible to communicate with the internal sensors from the OH (two bus masters on I²C?) so you wouldn't need an extra sensor in the OH. But the option of such coprocessor in the OH seems very well possible to me.
