Been using the Beta version of Intellij 4.0 on my last project. It is now on late release candidate builds and is fantastic. Previously I was an Eclipse fan, however this version has me sold.
Haven't tried out the generics support for Java 1.5 yet, but I've heard so many people talking about it I think I may have to see what the fuss is about.
Brian Coyner seems to agree with me in his review O'Reilly Network: IDEA 4.0 - Is It Worth The Money? [Jan. 23, 2004]
