In general, that's true, but if you've been thoroughly revitalized, matured, and cosmetically re-engineered, shouldn't you get a second shot at that first impression? I'd argue that's true of Oracle's Java/J2EE Workbench, Oracle JDeveloper. - Java Product Review — Oracle JDeveloper An IDE Worth a Second Look
