Using TextMate on Mac OS X. I love it. It's also very useful for many other languages and markups.
Hi Sandeep,
I’ve been using Arachno Ruby IDE; I switched from RadRails, because of the integrated visual debugger.
The IDE is a little quirky, but not difficult to get used to. The development is slow, but the product is robust. Very few crashes in the 6-8 mos. I’ve been using it.

I thought someone else would have mentioned this one:
I love textmate and my mac, but now there is a clone for all of you who are still on windows.

Yeah, I just switched from RadRails to this. It's still a little buggy, but I all I really want in an editor is syntax highlighting and the app tree on the side.
They only problem I ran into is that RadRails by default inserts spaces instead of tabs, so you have to do some refactoring.
