All I know is that my PS2 (I bought one at launch date) stopped working in a mere month and a half. It would no longer read PSX/PS2 games; just DVD movies and audio CDs. I had a 2-year product replacement plan on it from work, but surprise, surprise -- nothing in stock to replace it with for the two weeks I kept checking. So I ended up having to send it to Sony for repairs and I should be getting it back this month (at least according to them).
But guess what happened three days after I shipped my console? 87 new PS2 units arrived at my store. I was PISSED OFF. If I would have kwown to wait 3 more days (see, they never know anything about what's coming in stock as far as PS2s go) I would have gotten a brand new one right on the spot.
Anyway, I'm pretty disappointed with the QC of PS2s at least in the initial shipment. I'm not the only one that had this problem. Three other people's consoles at work starting doing the same thing. I know it wasn't the fault of my games either, because they all work flawlessly on my friend's PS2....
God, what ever happened to durability? Geeze, my PSX was abused A LOT and it never gave up until about a couple of months ago. It survived two mods, it was dropped from 6+ feet, the disc door was slammed down, etc. I treated my PS2 like a king and it craps out a month and a half. WTF???
