probably more a resolution thing than the cost of a
multiplication.

kernel gets only deltas at some fixed sample intervals
where the mouse can do it for every encoder cycle.
(no clue how its really done or with optical mice, touchpads
or trackpoints...)

but kernels software mouse acceleration works good
enougth, so we also have it enabled by default instead
of using the hardware one (which caused problems with
some mice on laptops).
