Boogie,
I've been involved professionally in the industry for many years...it wasn't all that long ago that Apeks had a deservedly bad rap for their regs. It wasn't until the "TX" series came out that they received a lot of well earned praise. They still can't sell many of their other products in this country. Their current regs are excellent and are the standard of the industry in many ways. Like I've mentioned in the past, if I wasn't so pleased with my Mares regs then Apeks would most likely be my choice.
Granted, the HUB was another solution to a non-existant problem. Many products are..including those from all of the major manufacturers. If you want to make a real point, then the original ScubaPro stab jacket could have been viewed in the same fashion. I, along with many others, were afraid of them back when they first debuted. Heck, at least two manufacturers produced wing style BCD's that fit directly on ABS backplates long before J. Jablonski was even in grade school. Swimaster made one that had the classic "U" shape along with a power inflator. Critics then called them a ridiculous piece of gear that had no future. I, too, agree though that the HUB's future looks pretty bleak.
The "evolution" of technical gear is actually nothing more that a cycle that has turned back.
In my opinion, regs have just about reached the point where the current design paradigms have reached full potential. The next big developmental step with almost have to include electronics of some sort.
