Java 5.0 and Netbeans

Yesterday, I started playing with JDK 1.5 (or Java 5.0) and the latest Netbeans IDE. I downloaded both from the Sun website, since they came bundled together.
My earlier impressions about Netbeans was that it was slow c0mpared to Eclipse or JBuilder. But the latest one seemed better. I am yet to find out more about it. But my first impression is that it has improved a lot from the previous version I had seen.
Java 5.0 has some good features adopted from C++, such as templates, enumerations, printf, varargs etc. Autoboxing is a good one. Nice features. Looks good so far.
