Windows Phone 7 wins developer speed race at TechEd NZ

Two teams of developers were challenged to create from scratch a cross-platform chat app for Windows Phone 7 and the iPhone, and rather predictably, due to the better tools available on Windows Phone 7 platform, the Windows Phone 7 team finished well before the iPhone team did.

Windows Phone 7 has won similar races before in a more neutral environment that TechEd, and many companies have reported that developing for Windows Phone costs  lot less because it needs less staff for less time.
