Query: Logitech io Pen

The idea seems good but for my general application I found it overkill and too much to use, in fact I didn't pursue it beyond initial partial installation -- I'm assuming that it works. Note that you have to use special paper which I would assume costs quite a bit. Alternatively I plan to merely scan a plain sheet of paper with writing or drawings and save it as a .jpg document using multiple indexing available in the Windows photo manager. If I want to extract a portion of a page I can use a picture editor.
