The letters page in the Artist has been discussing the merits of computer aided Art. I have found it of great assistance to me. First of all I just photographed my painting as a record of work then I played around with them. I think i improved and became bolder when doing Watercolours or Acrylics and saved a lot of paint in the process. Then i got an Itouch. i was on holiday on the move so i downloaded sketchbook pro and drew with that. Again i think it has helped me in my "real art" so my message is use whatever is out there. It is all useful and fantastic.
