In the course of your day to day business, there are many things that you might need to sketch or draw. 

Here are some reasons that you might want to draw something on your Tablet PC:

• Artists - create digital art on screen with a pen
• Graphic designers - create a sketch concept and share it quickly with your client
• Construction contractors - Create a sketch for your quote and pass it on to your team
• Engineers - Mark up plans on site in AutoCAD
• Insurance assessors - Annotate images and notes of damage
• Bored travellers - Doodle on the train or plane.

Of course drawing preceded writing as the earliest means of visual communication, and they do say that a picture is worth a thousand words. 

There are just so many things that you can’t put in words. But at least with a Tablet PC you can draw them without paper!
