Vasi&all, Flexible board technology is good for small places where the structure of the PCB must be custom, like a sandwich, a moebius or something else(small photo cameras for instance) and *not for prototyping or creating new applications* as arduino/jaluino was designed. Flexile PCB is sensitive to mechanical stress, once is heavily bent several times, it can brake.
If any of jaluino/arduino users have ever dissasembled an old HP photo-camera for repair purposes (it's like an arduino+ shield1+shiel2+shied3+halfshield4) they will never ever use again an arduino...
