It’s been known for a while that Microsoft’s smartphone platform — which includes Windows Phone 7/7.5 and the outdated Windows Mobile — has been holding at about 4 percent of the U.S. market.
Now Nielsen provides a breakdown of how much of that 4 percent is taken up by the old Windows Mobile platform — which Microsoft isn’t even pushing any more. And it turns out it’s Windows Mobile that has the larger share at 3 percent of the U.S. smartphone market.
Windows Phone 7 has a minuscule 1.3 percent, according to Nielsen.
Reviews have been generally favorable for the most recent Windows Phones but they have not broken through in the marketplace. Microsoft acknowledges the problem and says it’s a marketing challenge. While the company has signaled that it plans to make more aggressive moves to get Windows Phone into businesses (with the business-ready features of the upcoming Windows Phone 8), it has yet to say anything specific about what it’s planning to do to address the marketing problem.
It’s also interesting to note from Nielsen’s chart that HTC and Samsung both hold a bigger share of the Windows Phone market than Microsoft’s tightest phone hardware partner, Nokia.
