There's absolutly no mention about the pressure sensitivity level on Dell Inspiron 13 7373 + Dell Active Pen.
It's very important aspect when choosing touchscreen products with stylus.
Also, which pens do exactly work with Dell Inspiron 13 7373 and are they all have same pressure sensitivity level?
The system has a touchscreen - not a digitizer, so it's not going to be pressure sensitive at all.
If you want that feature, the only Dell that has it is the 13" XPS 2-in-one (XPS 9365).
I don't know about the pressure levels on that pen but the 556 and 557 have 2048.
That Pen does not do Bluetooth like the more expensive pens but I do not know if the more expensive ones will work with your system.
enj63, the newer systems (even Inspirons), especially 2-in-1 systems, are arriving with digitized screens. There is not enough information on the Dell site to determine what the differences might be between the QHD+ XPS 13 9365 and the FHD Inspiron 7373 2-in-1.
