OK, so I am old enough to remember carbs on cars and trucks. Back when the majority of the transformation to FI was happening, of the new cars available, hi-performance cars were FI, while low performance was still carbed. Many folks were rebelling and pulling the FI off and replacing it with carbs. In extreme cases where reliability and repair ability were major factors (such as boats and desert off-road vehicles), carbs were preferred.
As time went on and reliability went up, cheaper and more reliable electronic versions became available until just about the whole of the auto and much of the marine industry are FI. Only the motorcycles and lawn equipment have lagged technologically speaking.
Sure the change will be painful and initially expensive but really, with the cost of fuel today, would you really rather have your '68 Dodge Van with a 360, no A/C and 6 MPG or a '12 Ford Quad Cab with every known option and 25 MPG? Increased performance, directly due to improvements in fuel delivery, allows for smaller and lighter drive trains and engines.
I hear ya...it is more complicated. There is more to go wrong. It is more subseptible to heat and vibration. However the benefits far outweigh the risks.
