According to the rules, all of a character's cybernetic implants completely shut down for an entire encounter if even a single point of ion gets past their soak. That completely ruins the point of cybernetics for all characters. Why spend $10,000 on an extra point of Agility or Perception if you can immediately be made into a blind paraplegic for an entire encounter because a single point of ion got through? Taking a cybernetic implant is basically the same as reducing your strain threshold to 1. That seems rather harsh, and I can't see any reason anyone would ever take a cybernetic implant under those conditions .
It's even worse for droids, in that one of their main features is based around being able to equip up to 6 cybernetic implants. But with the current system, the more implants you have, the more screwed you are if even a single point of Ion gets through. Droids are designed to use cybernetics, but punished severely for doing so. If they have even a single major upgrade (such as brain, arms, or legs) and that 1 point of ion gets through, they're toast. Now imagine they've got all 3, as droids are designed to do; it's one of their major features; one of the reasons they start with less XP than other races.
The main argument I read in favor of this system is that +1 to a stat is really good, and so the penalty should be severe. To that, I say look at the other items you can get for $10,000. For that money, I could pick up Laminate with a Vacuum Seal, Superior Customization, and Enhanced Optic Suite. Sure, that's equipment, so it can be stolen, destroyed, or lost, but at least it won't crap out if you get nicked by an ion blast, and it's arguably way better than a bump in Brawn or Agility.
There should be some sort of drawback to balance things out, so every game doesn't turn into a party of cyborgs fighting their cyborg enemies, but the current drawback is so severe that it completely defeats the purpose of taking the upgrade in the first place. Am I missing something?
