Of all the problems that the Windows Phone 7 has been having, I’ve only seen ONE common culprit and it hasn’t been Microsoft. You know who’s REALLY responsible for marketing phones? PHONE companies, Manufacturers and maybe then maybe the Software company. Who’s been selling phones like hotcakes? HTC, LG, SAMSUNG, AT&T, Verizon, Sprint and T-Mobile (when they WANT to).
