Heh.
But who said it'd only effect mundane? There've been quite a few magical advances as well, from the Unified Magic Theory to the death of Channeling to new spell formulae... lots of room there.
Mostly, it's a GM tool.
"Here's a chart that you can roll on to set up, say, 12 months worth of SOTA. Once you know what'll be hot and what won't, you'll have a head start on adventure seeds."
Obviously, they'd be optional rules. Nobody wants to have, say, a Samurai Tax. But there should also be a mechanic around for those who want to portray the constant push for upgrades.
If nothing else, you have to make your deckers cry. (Aw man, I just *bought* that new I/O speed, and now there's a new FASTER type rolling out in a month? Awww...)
