My original PS1 still kinda works, although you have to place it in a weird angle for it to actually read any discs, which seemed to be a common problem with the console.
My old fat PS2 ended up dead after about 7 years when the disc drive no longer read anything. My second PS2 is still working perfectly.
My first 2 PS3's also ended up breaking, but my third has now been in use for over 6 years without any issues.
I also have a PSP that still works after 8 years.
We also have a 360 that doesn't belong to me, but it has worked perfectly thus far.
The best of all, my 25 year old NES still works.
So, for the most part I've been lucky with my consoles.
