None, despite 20 years of gaming I have yet to kill one yet.

The only system I've had break on me so far is the original Playstation. The original model was practically made to fall apart.. I went through 2 of em and then one dual shock model. Last I tested(2 months) my PSone still operates fine.

I had a Mega Drive (Genesis) [sold], Game Gear , Saturn , Dreamcast , Gamecube and a PS3 and never has a console stopped working on me.

I've owned numerous consoles over the years, and the only one that ever broke down was my Xbox - Error code 13. :(

My Nes doesn't really work.
My genesis stopped (partly my fault if not completely)
My big ps1 died
My big ps2 and first slim died (the slim died after 4 months)

My dreamcast died, it was a sad day.

Does that really work? Why would that method work? Do you know?

I wish I could try it on my Saturn, unfortunately it's a few thousand miles away from me at the moment...though I have been looking at picking up a used JP Saturn sometime. I just bought a used Super Famicom a few weeks back. :)

 basically.  I had 2 PS2s that broke on me... only consolse i've had to break on me and i have a working NES, SNES, Atari, gameboy and a Balley Astrocade.

Nearly all my playstations have crapped out on me.
I have broke 2 Ps1s, 2 Ps2s (also sold one just before it broke haha), but my Ps3 looks like a trooper, it's built like a brick shit house.

On a lighter note though, all my nintendos, dating back to the nes, are all still in perfect working order
