The innacurate pointer as you've described it, is normal.
This is caused by the digitizer doesnt know exactly where the pen is.
I'm fairly sure that with higher resolution tablets you will have less of
this problem... knowing that there are more points being activated...

"Distortions can occur especially at the edge of the sensor when combined
with an LCD, because many LCD's have metal frames around them"

Down neear the bottom it tells about the error correction near the edge,
which doesnt work too well with LCDs on top. Also shows how it works, and
how its layered.. rather neat!
