One word: expensive.
Refreshable Braille displays do exist, and even the cheapest functional
ones make the current cost of the Neo look like pocket change.
Incorporating this sort of technology into the Neo would not only be
expensive, but the mechanics of these things require a lot of
maintenance, not a fun thing to have in a phone.
While refreshable Braille on a touch screen would be the final goal
for accessibility, I think the OP was talking about mimicking buttons,
which I imagine wouldn't need to be nearly as precise. One 'bump' per
finger-space requires a much smaller resolution than six bumps per
finger-space (as is used in Braille). Mechanical movement is still the
challenge, but reducing the actuators by a factor of 6 is a big help.
