So to sum up, as voltage increases, the current can increase, be constant, or decrease, depending on whether it is a linear, non-linear, or highly non-linear devices respectively.

Absolute BULL PUCKY. Grab a scope at any point of time for any given load at that point of time if you increase the voltage across that load the current will increase. I don't care what the load is and I don't care at what frequency you are talking about. Ohms law is true - you cannot deny the math. Millions of engineering students each year try to inlabs all over the country - world. It holds true. With AC you have to take into acount inductive or capacitve loads - BUT Ohms law still holds true. I do not care if your load is constant is non linear.

EDIT -> I'm talking of external loads we use as hobbists. I'm not talking of internal loads within a switching regulator. I'm simply trying to get some basic principals taught so that most people can understand the relationship between volts, current, and resistance.
