When did you last try Eclipse on OS X?

I personally prefer Netbeans over Eclipse and Ubuntu or even Windows over Mac OS X, but Eclipse on Mac has become very usable since about two years ago. (I think there are still some problems with keyboard shortcuts, but I'll blame them mostly on OS X, not Eclipse.)

I've been using Eclipse for the last three years, more heavily in the last year (Android development). I find it to be incredibly slow, to the point where it becomes unusable. After a couple hours, switching files takes 2-3 seconds, code hints take 4-5 seconds, etc. Very painful.
