No Marketing no sales…. The same things I said back in March unfortunately still applies today. According to Comscore’s April 2011 U.S. Mobile Subscriber Market Share report; Windows Phone’s marketshare has slipped from 8% to 6.7% while Android has gained 5.2% and Apple 1.3%. Mango may be nice but if carriers and retail vendors don’t know what the heck is a Windows Phone then things aren’t magically going to drastically change any time soon.
