Hey, I still have a Commodore 64 -- and SX64, no less. They called it an "Executive Computer", and it was probably the first "laptop". It's the size of a big briefcase and HEAVY. The keyboard clips on the front to protect the 4 or 5 inch screen and the floppy drive. Still works, too, I break it out once every three years or so and spend an hour or so playing Pitfall. Thinking of selling it on Ebay for money to buy springs for the Challenger...
