As somebody who is a big user and proponent of Windows Phones, it's disappointing to see how Microsoft continues to fail to market the positives of the OS....specifically the deep facebook integration that we all currently enjoy. I did a quick google search for "best facebook integration OS" and there are no signs of Windows Phones. it's all about IOS6/OSX and their facebook integration. And to be honest, i don't think i recall seeing any WP7.5 ads/commercials that highlights how deeply integrated FB is.
