Nokia President and CEO Olli-Pekka Kallasvuo: The Full D7 Session

As President and CEO of Nokia, Olli-Pekka Kallasvuo runs the world’s largest mobile phone maker (with roughly 36 percent share) and one of the few top tech companies in Europe.

It’s a hard-won and enviable position, but a tough one to maintain, especially in a souring economy. And that is even more of an issue for Nokia (NOK) now, with new rivals like Apple (AAPL) emerging in the sector the company has long dominated.

Both Apple and Research in Motion (RIMM) gained market share at the company’s expense in the first quarter, with innovative touchscreens and apps, features that Nokia has been late to the smartphone party with.

Kallasvuo talks about all this and more in an interview with Walt Mossberg at the seventh D: All Things Digital conference.
