Tell me why I should or should not switch to fuel injection!!!!!!!!!!!!!!

I have cars with both, and I'm not sure I would do a FI setup again. It's been my experience, there is no real noticeable milage increase over a WELL tuned carb, and there are LOTS of parts to fail in a FI setup. I like both, but you can't beat the simplicity of a carburetor and a mechanical fuel pump.
