Microsoft may not be jumping on the dual-core bandwagon just yet, but it does place a high amount of emphasis on making sure its phones run smoothly. To do so, Windows Phone President Andy Lees stated to Bloomberg that it would continue to keep Qualcomm as its exclusive chipmaker, and has no plans to work with any other company. According to Lees, the monogamous relationship was made to allow Microsoft to use specific technical details, ensuring a smoother experience on all Windows Phones across the board. Lees also mentioned that the kind of production volume generated by such an agreement also allows production costs to dip down, which makes the platform even more appealing to OEMs. If any of you have dreamed of a Windows Phone with NVIDIA or TI running the show, don't try to pinch yourself -- you may be dissatisfied with the results.
