from linuxdevices story.
in a previous post i mentioned a cell phone with no display. it looks like gumstix has done that. a gsm module mated to the gumstix platform. rely on a bluetooth headset for audio in/out.
im not sure about a keypad. are the bluetooth twiddlers? ive heard some phones do audio digit dialing - speak "five oh three" to dial. that might work.
add an eye-glasses display and you'll be majorly borg-ing out. anyone got a link to small, inexpensive eyeglass display? monocle display would be fine.
actually a small display on the cpu unit would be nice. hmm i pretty much just described my trusty t39 phone. small display, bluetooth headset ready. weird.
