One of the best ways to keep track of the mobile ecosystem is through marketshare. iOS and Android are of course the dominant players, but it’s always interesting to see how well Windows Phone has stacked up. Unfortunately for Microsoft, marketshare in the United States over a one year period has declined drastically.

As you can see above, Windows Phone dropped more than a full percent down to just 1.5% of the marketshare in 2012. This data is interesting to note because the big push for Windows Phones hasn’t arrived yet. Nokia is set to debut its Lumia 800/900 in March with AT&T. Whether or not it will be the push Microsoft needs is debatable, but as it stands the ecosystem has no where to go but up.
