I have the red resident evil Xbox 360. I remember reading about how it was the least prone to the rrod. I just don't know if it's worth trading in to get the new slim.
Likely "least prone" because it was the least common. Might as well say the Simpsons yellow 360's were immune to RROD based on that.
Fewer units mean fewer failures. It took a while for people to realize there were an abnormal number of launch 360's failing and practically 33% of those were failing.
On the Slim, mine is silent. Anyone who compares this unit to the standard 360's without talking about the silence is seriously shortchanging the main advantage of this unit. The S in Xbox 360 S on the serial code is not S for Slim, it's S for Silent. I switched not for the new hotness, but for the new quietness. The whine is gone. Finally. I hope Microsoft never does that again.
