After a day of usage I noticed that the pen is miscalibrated. I calibrated it a few times and it remained miscalibrated. The "calibrate stylus" option in the settings does nothing! I tried it with unambigously wrong points and it accepted and the calibration remained the wrong factory defaults! It misses almost half an cm at the left and right side of the screen.

You could try installing the official firmware from September 2011. The pen works very well on my M90. I am satisfied with the way the device handles PDFs.
