This is all that comes to mind based on facts and not biased opinion. The things like RRoD and E74 seem to mostly be a thing of the past and no longer a disadvantage compared to YLoD and bad Wii lasers. I could be mistaken, though. Hopefully you find my post. I've tried to make sure these are 100% facts. I am a PS3 fan myself, but have tried to keep any bias out of this post. If there is bias, I'm sorry.
I have moved and do not have the internet at home, yet.
