In the mid eighties, I spent many hours in the lab at the University of Illinois, working through endless physics problems on PLATO. It was a great system. I'm jealous that I never had access to games on it. From what others have said, there was some serious fun to be had there.

Remembering the interface, I can't help but think that a port/remake would be a perfect fit for Apple's iThings. Just the nostalgia aspect would probably force me to jailbreak my phone.

None that actually "exploded", but I've had two motherboards go bad with leaking caps. Both are back in service after having most of the caps replaced. It does happen.
