I've never owned a PlayStation - always been an Xbox honk. I see no need to hate or pick one side or the other at this point.
This is a consumer's dream - two brand new, next-gen consoles that will more than likely launch in the same quarter. I pledge no allegiance to Xbox and will go with the console that best fits my needs. At this point I use the console as much for TV/Media activity as I do gaming. Can't wait to see how each will extend it's media capabilities (Netflix, Hulu, Mobile,etc...). I recently got rid of cable and am also hoping to see a better interface for NBA/MLB/NFL apps on the consoles.
Ultimately, we all win. Pick the flavor that fits your needs.
