Tempting though it is, I will refrain from piling on to the above posting since it is going off topic.

Back on topic...the US will be debuting the new $100 bills later this fall. It will be interesting to see how fast these will be recognized/ accepted/ required in Asia. Usually most Asian countries switch over to the new currency very quickly as a requirement. I remember during the last major redesign when the US went from the old-style Ben Franklins to the "Big Heads," that it seemed to take only a matter of a few months before the old style were no longer accepted and only Big Heads were. I suspect this upcoming switchover will work out similarly.

Therefore, anybody traveling towards the end of 2013/first half of 2014 and normally carrying USD 100's as exchange medium in Asia, should keep apprised of the acceptance situation at their destination. And if necessary, before leaving home, switch out your Big Heads for the latest and greatest.
