For many years I had a IRISPen. With new Windows programs use was eventually no longer possible. Now version 7 Express is a good and fast tool. Some practice must be to draw a straight, clean line over the text. With practice also succeed and the result is good. If you want to quickly scan a few times line and does not want to touch, is so well served. There used to be a holder to then the pen was at hand at the keyboard. There is not more, unfortunately. Now you have to come up with what, so that the cable does not pull the pen from the table.
