What would be the best app? (No. I'm not going to buy a wacom or any other traditional graphics tablet, but if ipad works fine, I might get Adonis jot touch 4.) Prospects: iGraphTablet Air Display Splashtop RealVNC MochaVNC iDisplay iScreen Screens ... Problem of course is that you have to buy these to test and there's not much comparisons in the net. I've tested iGraphTablet and it feels pretty laggy. I guess that ideal workflow for me would be, that I have big screen connected to mac and it shows the whole or half of the canvas and ipad shows a quarter or 1/9th or so. That way you could see wider picture on big screen, but more detailed view on ipad. iGraphTablet is reasonable when watching mac's screen, but the double delay to ipad's screen is too much. Is there any app that could use usb-connection to cut out wifi lag?
