I use the silver standard in my Pathfinder game, which means two things. First, when the rules or an adventure has me give out gold, I give out silver instead. Second, the price of all magic items is reduced by 90%.
The overall effect is that mundane items and services have more of an impact on the players, and it reigns in some of the ridiculous implications of the magic item economy.
What I want out of D&D Next in this regard is a reasonably well thought out economy where the price of objects makes sense within it, and where gold and silver aren't excessively abundant.
