To cut a long story short, if you're happy with virtualenv and pip then that's great, but the idea of pipenv is to replace virtualenv and pip, which means you'll actually have one tool fewer. :)

Genuine question: does pipenv do anything that [mini]conda doesn't?

[AndrewOMartin]

Everything you need to know about pipenv is in the linked talk. Sorry, I don't know anything about [mini]conda.

Does conda create a lockfile?

[kalefranz]

Not yet. But that's planned. See See https://github.com/conda/conda/issues/7248.
