Some obvious negatives I can think of: Slow speed (?), piston seal leakage,

Key word here is "SOME..."! Just imagine how many negatives if you include
the ones you CAN'T think of! Unless the hydraulic concept would provide a
FORCE somehow unattainable elsewise, and you NEEDED that force, or the like,
or, perhaps you live in a land where "cleaning goop off everything every hour
or so is delightful", Steppers or Servo would be the way to go!
Then again we're likely not to hear much about setups that allready exist.
Seems that the Quackers don't like electricity, but do just fine with hydraulics
in all sorts of things, including machine shops.....
