Microsoft today created a chasm between its mobile platforms in talks with Australia's APC. The OS developer's General Manager for the Mobile Business group's Asia-Pacific region, Natasha Kwan, revealed that all Windows Mobile 6 models, even very high-end phones like the HTC HD2, would be ruled out as few if any obey the three-button guideline for the Windows Phone 7 interface. The firm's Australia Business Operations Director, Tony Wilkinson, added that the HD2 lacks some unnamed hardware features needed to make the leap.
