I started using Eclipse at the beginning of the semester, and I really liked it. This isn't to take away from Eclipse at all, since it's a very powerful IDE.

Netbeans is the new hotness! It's subversion plugins actually work out of the box, the programming interface is CLEAN and easy to read. Did I mention how awesome programming within a group is with this software suite?Just read this page about how powerful the collaboration tool sets are! I'm a big fan. Total cost of ownership = $0.00. I just thought I'd share.
