I decided to give netbeans ruby ide a try for my new rails project, after having read a lot about it on blogs (especially this post on LifeOnRails). At first I thought it was a bit slow, but it turns out the nightly build I was using had some problems. I downloaded a new one (like 20 minutes later, yes, new build are coming out quite frequently!), and it was much better.
I have to say I was really impressed by the new NetBeans! I won’t go into details about it’s features here, the post on LifeOnRails did a pretty good job at that! But I’ll say this: If you haven’t tried it yet, you should!
