I consider the Unix command line to be my IDE too (I'm mostly a vim user). Just last night my plane was delayed due to heavy storms in Europe and as other peoples heavy laptops were running out of juice I still had hours left on my netbook. The command line is a great environment on low power hardware, it doesn't need a mouse and you don't have to wait for IDE support to start working with a new or obscure technology. That said, I still feel I need netbeans/jvi to do anything with Java -- personally I feel this is due to shortcomings with the language rather than a problem with the way I normally work. In fact, I recently started playing with Scala and, since netbeans didn't really add anything useful, I was able to go back to vim. I feel much more productive in Scala/vim than I ever was in Java/netbeans.
