Recently some analyst reported, based on some shaky Google Trends data, that Nokia Lumia sales are much lower than expected, although there was another article in Forbes yesterday, which cast some doubt on the validity of it. Today Nokia's spokesman James Etheridge said that "while it is not our policy to disclose individual product sales figures outside our quarterly financial results, we feel there has been premature sales analysis on the performance of the Lumia 800". Considering that Nokia Lumia 800 has been available in selected markets less than a week, I think it is fair to say these "analyst" have indeed been premature. "Based on earliest data, the sales start of the Lumia 800 is the best ever first week of Nokia smart phone sales in the U.K. in recent history", Etheridge said. According to Nokia, the Lumia 800 has received the highest score in Net Promoter Scores, which measure a consumer's willingness to recommend the product to a friend, of any Nokia device launched in recent history in the U.K.
