If this were coming from any other mouth, we'd definitely second guess it. As it stands, though, it's hard to dispute the words of Nokia's CEO when it comes to matters involving Nokia. Mr. Olli Pekka Kallasvuo stated rather proudly during the firm's Q4 results call that it had shipped just over 500,000 5800 XpressMusic mobiles (better known as the Tube) in just 30 days. That figure becomes even more impressive when you realize that shipments only occurred in select markets, though it should be noted that "units shipped" and "units sold to end users" could indeed be very different things. Still, half a million in just a month ain't too shabby in today's economy, so here's the kudos you're clearly due, Nokia.
