My 360 is a launch console. It's still running. On a rare occasion I'll get a red ring (though obviously not o' death). The disc tray sometimes needs to be jiggled a bit to eject. And last week the center green light on the power button was flashing until I reset the console. I kind of wish it would break so I'd have an excuse to get me a new low priced Elite for HDMI goodness.
Also my PS2 is a launch model in great working condition, though in all fairness it didn't work the day I bought it and I had to send it in to have the optical drive fixed. Been working like a champ since then, though I don't use it anymore because....
.... I have my launch 60 GB PS3 which I actually bought as a refurbished model for $300 a couple years ago.
Also my launch PSP still works though I need to find a 1st party replacement battery since I hacked mine and the 3rd party battery I have now doesn't last very long and doesn't tell the PSP how much juice it has left... it just dies when it runs out of power.
