Netbeans 6.5 is out. I just repeated the experiment and compared Eclipse IDE and Netbeans IDE using Google Trends. Regarding to the result it seems like Netbeans IDE became as popular as Eclipse IDE. It is just a statistic, but the situation has improved significantly for Netbeans IDE since the last measurement again. However, don't take it too seriously - the last post about this comparison caused 19 comments :-).
