I do have one concern that pertains to this very subject.  What happens when the miners begin to mine in the .00344 range or .000022 range?  I would try to considered the fact that the average person has trouble counting into the hundreds let alone the thousands and the numbers in the future will feel backwards to the average person.  This isn't going to make BTC obsolete or anything.  However, it by no means is going to add value to BTC.  What will we do?  Begin to browse Amazon for an item and try to purchase something with .000025 BTC?  I know this creates a problem.  Who has the solution?  Altcoins etc?  When does BTC decouple from the fiat?  LOLz BTC
