Out of an online poll of 42,000+ respondents, a whopping 76% responded in the negative AT&Ts question on whether they would buy a Windows Phone 7 device.
Considering how well Windows Phone 7 works with Facebook and Microsoft's deep connections to the social site (via Bing), those sure are some high negatives. Microsoft certainly has their work cut out for them, but this is a marathon, not a sprint. I'd also make some joke about teenagers and Facebook, but I think there are more older folk than younger ones these days. Could also be that they're thinking of Windows Mobile, not WP7.
