Like I said....I've never seen a Cube crap out. Not even one!!! I've seen 2 XboXes....this was due to faulty fans......and I've seen so many broken PS2s that I honestly couldn't count them all. We actually stopped guaranteeing PS2s, there were that many. In most cases, when we cracked them open, the insides were coated with a nicotine film and/or were filled with pet hair. It was hardly ever warranty due to manufacturers defect....but mainly failure due to customer neglect. The system wasn't designed to tolerate the ineptness of the general public.
If you have the technique down then the stock game cases are okay....but many people have this weird way of removing discs where they put their forefinger on the middle and their thumb at the edge of the disc and then sort of "pry" the disc out. Your fingers touch the surface most every time....or it fumbles out of your fingers, which isn't good for the disc. Go into any video game store and look at the condition of 90% of the used game department's discs. Scratched, scuffed and fingerprinted. Most people's game collections look like crap. It doesn't matter whether the disc "still works"....it isn't good for your hardware. We found that a CD case tends to be a little more manageable for the average person.
