Ive owned a few ps2's maybe 6. Traded a lit when I was younger. Never had a problem. Sure I got the disk read error. Cleaned the lens and it fixed it right up. My xbox and 360 both broke. In fact ive seen 3 other 360s break right in front of me. 

I had 4 ps2's - 1 for every room of the house- seems like overkill nowadays. Disk read error was an issue for 3 of them - not console breaking bad because it was easy to fix- but bad enough that we couldn't ignore it. But I remember people were making yellow light of death seem as bad as rrod... and no.. not even close. My almost 6 year old ps3 is still running fine.

You going to show proof?

Can find much more than a bunch of random post talking about 1-3 percent failure rate. I can't find any real prof that the ps2 has a high fail rate either. One can only concluded that it was in fact within acceptable industry standards. So going off of that Sony still has the quality down by a country mile considering the 360 was such a disaster. 

Speaking of hardware: The original XBox is a friggin' beast. Outside of the shoddy DVD drive that thing still runs like a champ for most people.

My guess is MS can't decide if they want to nickle and dime the headsets for small profit or just throw them in. I can't imagine these things costing MS more then $2 to make.

Can't conclude anything. Now 360 was a disaster don't have hard proof of that either but seeing as they sat aside billions to fix it we can guess that it was very high. I say PS2s were high and I'd bet anything it wasn't some 1-3% I don't even know where you're getting that from.
