Does Django need an IDE?
I use NotePad++, and have yet to need a fully-fledged IDE specifically for Django (though I do wish NotePad++ would stop periodically crashing).
I wouldn't, unless it was really really good (and I have no idea what features it'd need to make me enthusiastic enough to pay for it).
Maybe a neater way to tie together code for a specific app within a project (models, views and template code). NotePad++'s File->Open dialog is the Windows one, which picks up the directory from the currently open file. It'd be nice if it allowed me to switch quickly between related files.
My company is evaluating the possibility of developing a specialized IDE for Django. 
So we would like to ask Django users: 

Do you feel the need for a specialized IDE for Django?
Would you be willing to pay for it, or would you only consider free a open-source product? 
What Django-specific features are you missing currently in your development tools?
