So is this the "reminisce about console hardware failures" thread now?
I've had one Atari 2600 die on me due to being in a flooded basement - the other one I have still works.
My first NES died on me completely after 10+ years. I bought a refurbished one with a new 72 pin connector, and bought a spare 72 pin connector to back that one up in case it ever died.
My first SNES worked flawlessly until I sold it - the used one I replaced it with has generally worked well thus far, but I've had to tweak it a couple times to get games to run.
As far as I know my original PSX still works - it's an old enough rev to still have discrete composite out jacks - mainly because I coddled the thing like a baby after hearing all the horror stories about it. Always had it up on an egg crate or put floppy disks under the corners, that kind of thing. I haven't really used it since I got my PS2 since at this point I'd only need it to play my imports.
The used Saturn that I picked up for myself still works - played Guardian Heroes a week or two ago - but the cartridge port is extremely flaky (especially with my memory cartridge, boo), and I've had to replace the battery at least once.
I went through two Dreamcasts and at least three trips to the mall on launch day, as it took that many tries to find one that would run all the games I bought. Then it started to load really freaking slowly about two years in, so I replaced it for $99 and gave the old one to a friend.
Have had no problems with my PS2 since I got it. Only problem I've had with my Cube is that occasionally the controller won't work when I have it connected to both of the extension cables. Have had no issues with my Xbox or 360, except that the first Intercooler I bought for the 360 was DOA.
And finally, the first DS I bought had a dead pixel on the bottom screen, so I exchanged it.
