. Nokia (NOK) and Microsoft (MSFT) went all-out with the Lumia 900 when it launched earlier this year. For weeks it seemed impossible to go even one day without seeing a Lumia 900 commercial or a print advertisement, and early sales of the sleek smartphone looked promising. According to a new study from market research firm Strategy Analytics, however, Windows Phone sales will barely make a dent in the U.S. smartphone market this year. 

Strategy Analytics sees 123 million smartphones being sold in the U.S. in 2012, and just 4% - or less than 5 million - of them will be Windows Phones.
