Some people are actually suing over the interruptions.
Wow.
"Ahhh, my life is over! I can't log onto XBOX LIVE. I need to commit suicide now!".
Yes, a class action lawsuit because of server problems is that retarded. Hell, PAYING for access to Xbox live is retarded in the 1st place.
I dunno what the circumstances in that case are, but the Live server issues were quite the pain for me, and it didn't have anything to do with playing over the internet. (Well... It did that too, but that wasn't the big issue for me.)
I had to replace my 360, and MS DRM forces me to stay connected to Xbox Live in order to be able to use the hundreds of dollars of content that I have purchased.
During the Live issues, I was not able to play 90% of my Live Arcade titles, and my Rock Band content was inaccessible.
Don't think I would specifically sue because of service outages, but the thought sure has crossed my mind about that stupid DRM crap.
