Yeah, I keep waiting for the transducers, but they never quite appear.
Still using fingers to type, still using eyes to see.  I do so want a
mobile neural interface backed by a small mountain of processors and a
petabyte or so of RAID.  Transparent overlay of normal vision, noise
suppression capabilities of the ears, a few hundred movies, six month's
worth of music, all the e-books in the existence (all with a "dream
mode" where content is delivered at very low levels when I'm sleeping)
AND the the reverse ability to record dreams and create things in my
sleep.

Literally.
