In order to improve portability, it would be a good idea if the acquired data could be directly logged to some storage device included in the Bitalino. Ideally, it could be some optional hardware add-on, some sort of e.g. SD card shield, that we could connect to the already existing boards. I think it doesn't have to be super complicated at first: if the "shield" is connected, then data acquisition and logging starts once the power is on.
This is just a suggestion, but it would be very useful.
