Because sip is more complicated (as in overkill). I use basic types and simple 
C code. They do things like ioctls and SDL display. The way it is now I can 
have the swig directives in my normal header file so that foo.h and foo.c are 
basically all I need/have (well three times for manipulating three hardware 
drivers). I like to avoid any extra complexity as much as possible.

I can't verify your claims about speed and load time. I think they're broad 
and generalizing. I'm not having performance issues. If I would I'd move the 
offending code from Python to C (or consider pyrex). Compared to the GUI it's 
speedy enough. Besides, working with hardware, such as i2c devices for 
tuners, I can tell you that some operations are just dog slow by nature. A 
little python layer more or less between it won't even matter. I think in 
general you (well, I) can improve performance a lot more by making the GUI 
code more efficient. And of course by byte compiling all py modules.

It's my understanding that sip was invented to primarily wrap C++ and 
especially TrollTech's C++.

Anyway, this is OT... but interesting nonetheless.
