As egocentric about my experience you're insinuating, you're just as guilty. Sorry, but I have North America and Asian experience on my side this time. China, Singapore, Japan, United States, Canada, Mexico... Nokia's dwindling. And I did not see much 5800 presence in those areas.
In fact, I saw more N95's in Asia than 5800's. But in Europe... sure. Perhaps the 5800 sold well. One continent out of many isn't exactly faith-instilling.
You'd be under heavy denial if you did not pay attention to the fact that Nokia gave up in Japan and the US a very long time ago before the iPhone was mentioned.
