I can't parse most of this paragraph.

Once again, the dpi of the device has no effect on sizes written in
px.  Something 40px tall will be the same height on a 96dpi device as
a 300dpi device.  So, there is absolutely nothing to worry about in
terms of target sizes when displays get better.

The only thing that would motivate us to include more detail or more
options in the 'pointer' query is evidence that there really are input
methods for whom "coarse" (meant to indicate fat fingers on screens)
is still too small.
