Thank-you for that explanation. I'm not trying to be obtuse...
I didn't think you were obtuse at all, it was a valid question.

Full air brakes are a joke on wet/icy roads, use your gears or hang on and pray. I don't know where hydraulic boost fits, probably somewhere between vacuum boost and full air.
ABS has arisen due to technological superiority - no old-school system can individually modulate each wheel's braking based on its traction limit, independently of all the other wheels, and independent of the driver's panic level.
An anecdote aside from this discussion: The internet is full of 'highly-skilled' guys that claim to be able to outbrake ABS, but whenever I've asked, none of those keyboard jockeys would even discuss any interest to partake in a back-to-back test in a variety of controlled conditions, of them vs an ABS car. Would be interesting to see, and I'd eat crow if needed. But I don't think I would need to worry about that...

Fury Fan, no wish to contradict you, but that statement is not exactly true. ABS systems, have been around since the early '50's, although mechanical in those days. There was a US market only motorcycle sold in 1958, and had got their act together, a few years later (mid '60's) in a car. Electronic ABS systems were first used in 1966. So really, if the US auto makers had got their act together, at least some C Bodies could have had a modern system from new...

First ABS car I had was a '86 Buick wagon, didn't work worth a darn. Worse, G|M was experimenting with different types of master cylinders and I discovered mine was only available from GM and the repair was going to be almost 5 grand - I sold it.
The problem with the new ABS systems is not mechanical, it's stupid drivers that stand on the brake and forget to steer around the problem. The ability to maintain steering in a panic stop is the only reason to have ABS.
