Topic: Good, portable IDE for Ruby - any suggestions?

Hello,

I've started my adventure with Ruby recently.
Now I'm looking for good IDE that I can use to edit my code (Ruby scripts and Rails applications). It can be free or commercial (I don't mind spending few quids on it).

So far I've user RubyMine IDE and EditRocket - they are fine, but wonder whether there's something better?

My requirements are:
- portability (I mainly use Mac OS X, but also Windows and Linux)
- code completion

Any suggestions?

Thanks in advance.

Re: Good, portable IDE for Ruby - any suggestions?

Just saw the "Pim your editor" thread (http://railsforum.com/viewtopic.php?id=658), which pretty much answers my questions.
But pelase, if you know of something never or better, let me know.

Thanks,
K.
