I've been using PyDev for many years, for Python and Jython development of all kinds. The more recent releases have made some big usability improvements. Specifically, autocompletion works in many more cases, and the built-in refactoring support is proving handy. Rough edges that have bugged me for years are being steadily smoothed away.
So thanks for all the free stuff Fabio! If I was at PyCon I would buy you a drink.
