Stockholm has already produced Spotify and SoundCloud, and with nearly 700 high-tech companies located in its Kista neighborhood (Sweden's "Wireless Valley") the world can expect more tech innovations. The government spends on R&D (3.6% of GDP), and the country's world-class education system churns out a large pool of scientific publications and research. Intel, Symantec, and Oracle all have local offices, but lest you think Stockholm is studious and serious, please note that Angry Birds maker Rovio just opened a studio there.
CEO Mark Zuckerberg would like to reach the country's 513 million Internet users. Too bad local entrepreneurs have beaten him to the punch.
