Although I generally am happy with TextMate, an IDE would be useful for some tasks, especially debugging and code browsing/refactoring. I wish something like Ruby in Steel was available for OS X and Linux. I know there are eclipse and netbeans IDEs. They really suck. Other small players don't build a nice product either; I've tried them all. I would pay money for a solid OS X and/or linux based graphic debugger and "Smalltalk-style" code browser for ruby.
