So you're saying that maybe a few 100 voice clips are more than enough to take so much space and that they can't put atleast a 128GB the size of a micro SD card memory inside the computers in the R211s..
The 211s are really missing such a great feature that all the other NTT had.. they had a place to hold on to the gratings on the ceiling where the ventilation is.. it came in handy during packed trains and you're by the door.. idk why Kawasaki didn't add such a useful feature.
