Below are my consoles and the end results.
Atari VCS: Still works fine
Intellevision: Still works fine
NES: Had to replace the pins a few years ago, cost almost nothing and works fine now
Sega Genesis: Still works fine
N64: Still works fine
PS1: Stopped reading discs rather quickly, replacement stopped working too
Dreamcast: Still works fine
Gamecube: Still works fine
Xbox: Still works fine
PS2: Stopped reading discs after a few years (3 I believe), no longer works
Wii: Still works fine
PS3 OG model: Still works great which, given the previous two broke and it's backwards compatible, I'm very grateful for that
Xbox360: My first one broke almost immediately (2005-06). My second broke two years later(2006-2008). My third stopped reading discs 2 1/2 years ago (2009-2013). My roommate's also only lasted three years. I'm bummed that a solid, large library of games are unplayable now, but I'm just not up for buying yet another of them.
Wii U: Works well but I think the fan is a little noisier than it's intended to be.
PS4: Works just fine
In sum, my experience with Gen 2 consoles has been positive with both consoles despite the VCS closing in on 40 and the intellevision being in its mid 30's. Nintendo consoles seem very durable, the sole exception being an easily and inexpensively replaced new set of pins for the NES. Sega, likewise, has been great (though the Gamegear stopped working due to shoddy capacitors, been planning to repair).
Otherwise, Sony got off to a shaky start with me, the PS1 seeming flimsy (both stopped working) and the PS2 eventually facing similar problems, though it was a definite improvement. They really picked up their game, though, with that first model PS3 being a glorious, backwards compatible brick of awesomeness, and the PS4 seems sturdy enough so far.
As for Microsoft, I feel I could drop kick the original Xbox and the only thing that would break is my foot. The Xbox360, however was incredibly frustrating. Over the course of that generation I had three consoles stop working personally, and witnessed my roommate's stop as well. I've no doubt we were unluckier than most, but when you couple that problem with the flimsy feel, loud fans and weird noises, I'm glad to put that console behind me. That's really saying something as it had my favorite games, controllers, and online experience of the generation... I just wish the Xbox1 was backwards compatible as I have quite a library that's unplayable now, and that alone would prompt me to buy one.
So, in total, two PS1's broke, one PS2 broke, and four Xbox360's broke. Overall I've been quite lucky, though. :)
*edit*: Forgot handhelds... I have an original Gameboy, another gameboy, two gameboy colors, a gameboy advanced, a DS, PSP, and 3ds, and all still work perfectly. The only broken one is the Gamegear, and apparently that's almost inevitable.
