With last month's release of Microsoft's Xbox One and Sony's PlayStation 4, Nintendo, with its fledgling Wii U, has all but cemented its place as the third choice for gamers. With just 4.5 million units sold worldwide, the Wii U is far from the follow-up success Nintendo envisioned.
Comparatively, Windows Phone has had some success in 2013, but it still trails Apple's iOS and Google's Android platforms in mobile computing.
The Wii U and Windows Phone have some things in common that may be the reason for their struggles. Mainly, they both rely on their own software and lack strong support from third-party developers.
