Since Microsoft launched WP7 at the tail end of 2010, the company has been tight lipped on sales figures, though it was widely reported that Microsoft spent the best part of $400m advertising WP7 devices. Smartphone sales figures had shown Microsoft's efforts were in vain as its share of the smartphone market was slowly being eroded away thanks primarily to Google's Android, however finally someone has reported that WP7 has held its ground.
Although Microsoft has managed to halt the decline, the truth is that WP7 is near rock bottom as it is. NPD reports that Windows smartphones, which includes both WP7 and Windows Mobile, made up just five percent of units sold in the second quarter.
