Michael Mace has written what has to be one of the clearest market comparison articles I've read in a long time. Over on his blog he's gone into some wonderful cultural comparisions of the European and American marketplaces for mobile technology. Ever wondered why Nokia "has Rock Star status" in Europe yet is "lost in the crowd of semi-anonymous Euro-brands" in the US? Why number portability is king? And why not to ask a European Operator about MMS revenue?
