Just as a counter point, I was a huge fan of the changes in version two. "Wizzy and interactive" can be incredibly important for a wide range of applications. Half the reason interpreters are wonderful is that they drastically reduce the "idea to running" time, and having interactive widgets can do even more for that. (Not to mention things like animations and UIs, which are just useful sometimes.) Similarly, notebooks are a great way for me to publish content, and a very large portion of the things I write are written as IPython notebooks.
As an aside, everything in IPython 2 is available from the keyboard and all shortcuts can be viewed by pressing the Help menu or 'h'. 'Add cell above' is now just 'a' (and below is 'b') when in command-mode. I expect that learning to use the new modal interface can be a bit of a hassle, but for me it turned out to ultimately be really awesome.
