When I was in the first class of high school, the most powerful available PC was a 486DX2 66MHZ with 8MB of RAM.
This clarification is necessary to understand the following dialogue:
Me: "What computer do you have?"
Dude: "A 486 at 66MHZ"
Me: "HOLY CRAP! And how much RAM do you have?"
Dude: "What do you mean?"
Me: "The system memory! How much do you have?"
Dude: "Oh, sure! It's unlimited"
Dude: "Yeah, right, unlimited"
