I found a whole group of people who ask how to convert their android tablet into a "cheap" drawing tablet. What surprised me as that there means of doing that. They are very complex though. You can fix it that lines drawn on your tablet screen will appear in a drawing application on your computer--if you want. I have a simpler suggestion though. You can download a free drawing app on your tablet and draw away and paint. There are color mixes and a lot of controls. Then save the drawing. These apps support e-mailing the drawings to yourself as jpgs. These jegs will simply arrive in email and you can use your PC drawing or paint software to touch it up.
