I use pypy as a drop-in replacement for CPython for some small data crunching scripts of my hobby projects. Might not count as "real work", but getting "free" speed ups is very nice and I'm very grateful for the PyPy project for providing a performant alternative to CPython.

I was close to trying pypy on a production django deployment (which gets ~100k views a month), but given that the tiny AWS EC2 instance we're running it on is memory bound, the increased pypy memory usage made it impractical to do so.
