Personally, I've been lucky. Though I have seen sparks while plugging while powered. Also I've got many broken systems where at least one port (of two) was broken, but could be compensated by 'Y-wire' where you'd put mouse and keyboard via that Y-wire into the remaining port. Which later became some sort of pseudo-standard, cost cutting, because only one port is cheaper? I also seem to remember advertising on the package of better boards, which had protection against that.
