Digitizer vs Stylus

Question
"What is a digitizer pen and what's the difference from a regular stylus?"

My answer:
A digitizer is an electronic device, the stylus is not. An electronic device can be defined as a pen that has it's own electricity, uses magnets, or draws power from an external device in order to function. The digitizer offers things like: hover state, pressure sensitivity [from the pen], multiple buttons, eraser, etc. The stylus offers: an emulation of a mouse/touch click/down. Most pens used on iPads/Android tablets are styluses (Pogo,amPen), but many Windows systems have had styluses... also the now ancient Palm organizers and Pocket PCs known as PDAs (Personal Digital Assistants) had styluses. Digitizers are often found in many Windows and some Android systems and they are regularly based on technologies by Wacom, N-Trig, and Samsung's S-Pen.

If you have a choice then I recommend using Wacom based as many of their devices produce better line quality results (in some devices up to 2048 levels of pressure).  Although, at the moment of this writing, N-Trig is about to introduce their next generation digitizer technology (DuoSense Pen 2).

Other pen technologies: Atmel, Synaptics, Hitachi.

  1. I have fixed a huge LED monitor on the wall, so that I may watch musical videos to entertain myself when I tired of work. You can find plenty of monitors at http://www.whatisrightforme.com/monitor/
