The tablet has thus lost its appeal for me. Its primary purpose should be to take notes in university lectures all digitally via OneNote.

Apart from the pin problem but you get a well-made and fast device.

In addition, the online Syncronisation notebooks works great, also you can perform font & Formula conversions, scribble scripts, Print, just everything a real Windows computer.
