This would be suicide for any Android phone manufacturer. I love my Samsung phone and I think Samsung has been making phenomenal devices but I would replace it in a hearbeat if it was packed with Bing apps instead of Google ones. Samsung saw the hell Apple went through for using their own Maps. They would never make the same mistake by dropping Google maps for Bing Maps.There's even a possibility that Samsung could "fork" Android and cut out Google services altogether, thus reducing the revenue trickle by using Bing Maps and Bing instead.
Earlier, in Google HQ:Just before Christmas, a report from Reuters claimed that Google is working closely with Motorola to develop a smartphone that will grab market share from both Apple and Samsung.
