I’m with you on this one Bill. As you say, contacts are typically the most unreliable part of any electronic device. One extra set of contacts (gold or not) is one more potential point of failure - simpler is better.
Back in my lab days, where we had about 40 Macs and 120 PCs running the place, we ran into contact issues frequently.
> Several new custom-built high performance AMD PCs momentarily caught fire because they were built by small shops who did not understand the thermals involved when rendering JPEGs flat out, 24 hours a day, seven days a week. Their power supply connectors to the motherboard melted, causing shorts, burning the motherboards. Replacing them with high-spec Dells with dual Zeons solved the problem. (If you're going to over-clock an x86 processor and run it flat out, be sure the motherboard can handle the Wattage, and that the cooling is sufficient to cool EVERYTHING under a sustained full load.)
> A bad batch of hard drives in an order of 50 Gateway office computers was ultimately traced to poorly-made connectors that did not contact all of the pins on the drives. Gateway had to replace the wiring harnesses and the drives in 50 computers!
> Bad memory slots in six Power Mac G3 computers led to early failures. This was a known problem that Apple fixed by replacing the motherboards. They were gold-plated connectors that just didn't grip the memory DIMMs! Oddly, the same one of four slots in all six Macs was defective.
> We had a dipstick in IT who built 12 servers for our four labs, from off-the-shelf parts. The parts were good, but he was a klutz and didn't seat the various cards and connectors properly. He actually broke several cards — two network interface cards and a drive controller card, and damaged some cables. Three of the four servers in our lab (the others were in three other labs we had then) appeared to function normally, until we needed the data for production. It was CORRUPT. The fourth server never did work. The local IT managers in all the labs determined what had happened, and the culprit was summarily ushered out the door by the beleaguered IT director. $156,000 later, we had HP servers that worked.
I wish I had five bucks for every bad, loose, broken, incorrectly wired, corroded, or otherwise faulty connection I've seen over the years. I'd buy my wife an expensive dinner.
