Actually, gold and silver

Actually, gold and silver would require some education, because the vast majority of the public have no experience in recognizing a real coin; and would have to consult an expert or Wikipedia anyway. That learning curve might not be difficult, but it is real, and would be an issue if we were to ever had a SUDDEN need to change our monetary system. Bitcoin does have a steeper learning curve, with the current clients, but that can be expected to be mitigated as the economy grows and more user friendly clients are developed. The one I have on my android phone, BitcoinSpinner, is as easy to use and understand as any other android app; so if you can manage a smartphone you can use bitcoin.
