I was considering passing on the next gen consoles but Xbox One will be day 1 purchase. Loving the TV, Skype, multitasking, kinect 2.0 integration for the big screen in the living room. I know my HTPC can do the same, but its hell of a lot more messy and you still have to deal with a keyboard and mouse of somesort...
In terms of gaming, nothing that interests me was shown, but the new DRM has absolutely no effect on me.
