Eclipse is getting worse with every release... Unstable, Features not working, difficult to configure certain perspectives (PHP), slow like hell (try developing something having ZendFramework in the include_path), crashing sometimes, issues with SVN out of a box... Yet it's best IDE I've managed to find... the only one that is better is Zend Studio - but it's not free - so sort of - out of range... I cannot say Eclipse is BAD... it's not... it just lacks the "integration" and "smoothness" - that evil MS gives you when it comes to their Express Series...
