If you have a ruggedized tablet you can take notes by hand, use the on-screen keyboard, or even draw from time to time. The correct type of pen is a huge benefit and allows for precise navigation on the handheld display. If your tablet has a digitizer, you will need a digitizer pen, not a regular stylus. MobileDemand can provide you what you need for your commercial tablet. Digitizer pen pictured may be a different model than what you receive.
