I think if they had waited to do this after Kinect and ESPN stuff was out, the community in general would be a little cooler about it.
The part that was kind of funny, though, was that in the official PR releases they didn't even really try to spin it. They basically said "Xbox Live is the best online service out there, we're raising rates a little bit, gamers will be willing to pay it because it's the best." in slightly different words.
