Great on an iPad
Works really well. Cut & Paste external code with no problem. Handles everything but 3D output environment. Lots of included documentation like a command library and Arduino interfacing. Can write, load and save new code and use both portrait or landscape orientation (with size(screenWidth,screenHeight) command). Many example programs and 5 different fonts included. Non-movable bottom screen taskbar hides println output & error messages. This should be fixed. Overall excellent for anyone with little or no experience with Processing programming.
