I could very well be an anomaly, but I don't want to utilize a game device in which I have to associate my Facebook account (yes, I still have one). I don't care how fast you get it to market or how much lower it will cost. I don't want to login to anything with my FB credentials, there is too much personal information in the weight of that authorization. Way more than what I want to give to play a game (and I do love gaming).
And Yes, I have a hollow Hotmail account that is linked to my Xbox Live account - however I like to try to keep everything as segregated as possible. Its a constant battle to keep my information hubs segregated and this acquisition is one step closer to me just abstaining from certain tech that makes me cross hubs.
