In a wide-ranging interview with Ars Technica, Estonian President Toomas Hendrik talked about European Digital Single Market (DSM), an ambitious goal that seeks to make commerce flow as smoothly across the 28-member block as it does in the United States. He cites the example of iTunes. From the report: What Estonia and Finland are doing is a step towards the DSM -- but there remain all kinds of national-level laws that stop Europe from being truly unified. "Take iTunes," President Ilves continued. "iTunes are based on credit cards. Credit cards are national. I cannot buy an iTunes record for my wife who has a Latvian credit card. I cannot buy her an iTunes record because I have an Estonian iTunes. This is true of virtually everything that is connected to digital services. And certainly this is why Estonia is at the forefront of the European Digital Single Market. As I like to say, it's easier to ship a bottle of Portuguese wine from southern Portugal in the Algarve and sell it in northern Lapland, than it is for me to buy an iTunes record across the Estonian-Latvian border."The report is worth a read in its entirety.
