I've used the JavaScript Anywhere app (https://www.javascriptanywhere.net/ https://www.javascriptanywhere.net/) on my IPhone to experiment with algorithms and write useful snippets of code during my commute. It works fairly well with the two obvious limiting factors are screen size and clunky keyboard input. However, the #1 stumbling block is lack of cursor navigation. It desperately needs cursor keys and shortcuts to move to the beginning/end of the line. The #2 greatest frustration is having no good way to select text except fat finger selection. What's needed most is an extended keyboard (w/ cursor keys, for example) and/or a smarter popup "magnifying glass" mode so you have a bigger target for fat finger selections.
