I tried drawing on my new mini iPad. I've tried doing many things on it, but there are no instructions (the bastards) so I just perspire. However it was interesting to try it, because I am used to sketching the traditional way, and now sketching the traditional way suddenly felt like ice skating and all I could draw were very rude things and it was all over very quickly. As above, I suspect the sketching functions on these apparatus, or applications, turn what used to be 'lightning sketches' in to something approximating carving granite, and all you can do is slip and slide like Scooby Doo! McLuhan was right, the medium is the message, or massage, and in my case, clearly a zipless fuck.
