Soon pypy will be compatible with numpy and scipy. Also it is interesting what other stuff you can now do with pypy, for example pyglet runs on it - think opengl 3d and 2d games - should be fast enough for many games, you can run pyramid web framework on it with great success including database drivers, so webdev is already possible - i've made some benchmarks of index page for my application and got 4x speed increase request/per second wise - without caching. So while its not ready for everyone yet, it may be ready for you, so don't think about it like some exotic thing no one will use it.
