re: Will Windows Phone Take Off In 2012?
I don't think it will take off. 1) There is little ISV/developer support. 2) There is no OEM (cell phone manufacturer) support, expect Nokia due to Microsoft's billion plus subsidy. The OEMs have witnessed how the Microsoft model has worked for the PC OEMs (HP, Dell, Lenovo, etc) and they do not want any part of it. The OEMs will never climb aboard as long as Microsoft does not allow them to alter the interface or functions which puts them in a commodity market where they are hamstrung to differentiate themselves from their competitors on technology and need to compete on price. Microsoft will also need to get much more generous with their profit sharing than they are with the PC OEMs.
Also, like it or not, smartphones are fashion accessories where the hipness of your brand matters almost more than feature/function. It is difficult for anyone to come up with a function that they need to have on iOS that is not on BlackBerry or vice-versa (or Android vs. iOS). Microsoft suffers from a serious cool factor deficit vs. Apple and the Android devices.
