HTC First discontinued on AT&T

I'm really just posting this because I'm suprised not to have seen it yet on The Verge. Yes, after a whopping long month, AT&T is apparently canning the HTC First. Just want to open it up for discussion really: Does anyone own one? Why do you think it didn't take off? What, if any, are the larger ramifications for Facebook as a service and as a business?
