I agree from the bottom of my heart. In the past I've used Pyrex Cython 
for wrapping libraries and small snippets of C speedup with great 
success. The learning curve is smooth and experiments show quick success.

Once Cython's development has slowed down and stabilized I like to see 
its usage for non-critical extension modules. Cython should make it 
easier to write wrappers for libraries or the IO performance improvement 
module, Amaury is working on. However I wouldn't want to use it for 
anything critical to the core of Python. I like to keep that C code of 
the core as readable as possible.
