After reading your post, I think that this video is a (fairly) accurate tl;dr summary.
The Escapist : Zero Punctuation: Console Rundown
The only console of the three new one+s that I have not yet played is the playstation 3, though I don't think that there are that many games that can't be played on the 360 to warrant buying it. I'm happy with my 360, I'm happy with both the games I currently own and the games that are available. I like the way xbox live runs (the 50$ a year is tiny for what I feel I get). This is the first system that I have been able to play with other people I don't know on, and its alot of fun (every once in a while you get a 12 year old that just learned the+ words '****' and '******', but its not as if that is any worse than PC gaming).
I think that the WII and the PS3 have the ability to be good if there were any games worth paying $60+ for.
