I don't understand the question.

I use emacs, with cperl-mode and fontlock-mode colourizing the fonts. I find it convenient for quickly detecting missing close quotes and such.

There's syntax highlighting for vi, though I don't use it there.

However, if the topic were languages that can't be used outside a complex and slow IDE, that would definitely disrupt my ability to develop anywhere, anytime, even over a slow dial-up modem. I understand you can connect to a server with a BlackBerry and get some work done, with vi, but not with Eclipse... or did I misunderstand that part>
