Same here. I work in the systematic trading business and I gave Notebooks an honest shot, but in the end using Pycharm and scripts along with the ipython console is the best workflow I found. I can easily send blocks of code to the console with a single keypress inside Pycharm, making interactive work a breeze. However, all my code is in nice idiomatic python files that can be imported, refactored and easily version controlled. The same workflow can be done in VIM, Emacs or pretty much any other editor with an ipython console integration.
