Losing the Koala pad readings in between as you describe does indicate
that the Apple isn't sampling fast enough...but this is a problem in
the software you are using.  I have used Logo, Pascal, and Basic to
take Koala pad (and joystick) readings...Logo is slowest.  I've used
some fancy Koala pad software that I think came with the pad...its
sampling routines are probably in assembly, and it hardly ever loses
readings.

Once, I used a cheap VOM to see how linear the pad's readings were with
respect to pen position.  I'd say the limiting factor in that case was
the needle response in the VOM, never the pad.
