I had a launch 360 until the slim came out... had RROD once (likely my fault for how it was locked in a cabinet and overheating)... fixed it myself.
A Hard drive can fail in a PS3 as well... so if you bought a PS3 to avoid hard drive failure I'm not sure that's a good reason... PS3 also had a big string of blu-ray drive failures early on... not as widespread as the xbox problems but unlike MS, Sony charged for all repairs.
That's like me saying I have xbox because PSN online gets hacked and I don't want my CC info stolen....
