Obviously you are more concerned with having a free service than having a better one. That's fine and that's your prerogative. Still doesn't change the fact that XBL is a better service and some people find that service worth the money.
What are you gonna do when Sony charges you for their mediocre service this generation?
I had Live when I had my 360s. The ONLY thing I like is being able to jump in a friend's game, everything else is preference.
