More software developers should follow the lead of Adobe and Skype, which have abandoned Windows Mobile -- what Microsoft now calls Windows Phone Classic. The mobile operating system already was brain dead, even with, according to Gartner, 15 million unit sales in 2009. The heart pumped out licenses, but there was no brain activity to keep the platform going. Windows Mobile flatlined, and it's about time that some Microsoft developers admit it. Others should get over the denial and do the same. Microsoft doesn't have the courage to pull the plug. But smart developers can.
