Many people want to use their iPad as a Wacom or a doodle board, but they soon find out that the touch screen doesn’t react to anything but the slight electrical conductivity in the fingers which controls the clicking and scribbling. A lot of people have pointed out that this will be the downfall of the iPad, and that Apple should really look into the matter and make a more universal screen for people who want to use their iPad in a more creative way.
On the other hand, some people just won’t sit around waiting for Apple to correct what wasn’t a flaw, but a strategic decision from the beginning. These people are called technology hackers more than inventors. A group of these people working at Teague has discovered that if you go about it in a different way, you can still have your iPad and use it as a Wacom or a doodle board also.
The solution is genius. It will probably set you back about $2 if even that.
