Yes, the irony is very fitting, because as we all know some evil masterminds at Apple HQ are all about making it difficult for non-conformists to have credit cards at multiple countries.
Or you could arrive at the rational conclusion that dealing with different countries, tax systems, economic agreements, copyright laws, regulations, accounts, currency exchanges et cetera AND tracking all that is
_so_difficult_
that despite being a very lucrative outcome for those who manage it, VERY VERY few entities have managed to somewhat overcome those problems a worldwide basis. Namely, Paypal (I did say "somewhat"). And this bloody mess has nothing to do with Apple or any specific company.
Just because we got worldwide connectivity via the internet 20 years ago, people expect boundaries between 200 countries with widely varying economic systems, allies, agreements they participate in, level of technological sophistication, willingness to change their laws, etc etc, will suddenly be unified into one harmonious system so that people can have iTunes accounts in both California and the Congo?
